&lt;p&gt;An entry at &lt;a href=&quot;http://www.illuminatedmind.net/&quot;&gt;Illuminated Mind&lt;/a&gt; has struck a chord with me. It&#x27;s titled “&lt;a href=&quot;http://www.illuminatedmind.net/2009/03/04/if-its-a-good-idea-dont-do-it/&quot;&gt;If It’s a Good Idea… Don’t Do It&lt;/a&gt;”, although “If It&#x27;s &lt;em&gt;Just&lt;/em&gt; a Good Idea…” captures the message more clearly.&lt;/p&gt;
&lt;p&gt;One of the reasons I petered out of university was that I was doing it &lt;em&gt;only&lt;/em&gt; because it was a good idea, and not because I was still passionate about understanding the physics. Even the dead-centre-of-my-field-of-interest module of Cosmology was failing to inspire me.&lt;/p&gt;
&lt;p&gt;It wasn&#x27;t at all &lt;em&gt;arduous&lt;/em&gt;: I still came upon flashes of epiphany every so often—one such I recall involved the insight that the constituent particles in atoms&#x27; nuclei are &lt;em&gt;also&lt;/em&gt; arranged in shells, like the orbiting electrons, and that shell boundaries could explain some discontinuities in each element&#x27;s differing physical properties—but they were too few and too far between to hold my interest.&lt;/p&gt;
&lt;p&gt;I also realised that I wasn&#x27;t especially good at maths, and the solid intuitive understanding of maths needed to grok the physics I was learning was just slightly beyond me. Perhaps I stopped caring about maths too.&lt;/p&gt;
&lt;p&gt;I realised that I only cared about qualitative trends, and not about the process of calculating results from formulae, or being able to properly derive a formula from memory and a set of more fundamental equations. Once I knew that formula C necessarily followed from formulae A &amp;amp; B, I was happy. I still like unscaled graphs as qualitative illustrations.&lt;/p&gt;
&lt;p&gt;The main thing I cited at the time was &lt;a href=&quot;http://www.hbo.com/sixfeetunder/&quot;&gt;Six Feet Under&lt;/a&gt;. &lt;a href=&quot;http://www.channel4.com/more4/&quot;&gt;More4&lt;/a&gt; were showing repeats of the later series late each weeknight. I decided that the characters&#x27; philosophical discussions (perhaps combined with the late hour of the broadcast) were expanding my mind more than rigorous study of science.&lt;/p&gt;
&lt;p&gt;I never particularly wanted a degree—I just wanted to learn about the universe. And I found myself gaining more insight into the universe by following the fictional escapades of a family of intelligent undertakers than by computing physical quantities.&lt;/p&gt;
&lt;hr/&gt;
&lt;p&gt;So I was doing what was a good idea, rather than what inspired me. I&#x27;d made a similar decision before, when I chose to carry on Religious Studies to full A-level in college, instead of continuing to study Chemistry, despite doing slightly better at chemistry in practically every respect.&lt;/p&gt;
&lt;p&gt;The difference was that in &lt;em&gt;that&lt;/em&gt; case there&#x27;d been a fire for me to jump out of the frying pan and into. Watching Six Feet Under is not a full-time occupation.&lt;/p&gt;
&lt;p&gt;So I bummed about a bit, not even looking for a job for the next few months as I had some spare student loan and overdraft to play with.&lt;/p&gt;
&lt;p&gt;I eventually happened upon a desk job that suited me down to the ground: opening letters, filing, sorting and being a general administrative office bitch, for the customer relations department of a train operating company.&lt;/p&gt;
&lt;p&gt;The work itself was easy and almost entirely stress-free, as I always had someone to turn to when in doubt. I continued to devote much of my mindshare to the day-to-day happenings in software and technology news (an interest I can trace back to the buggy implementation of CSS in Microsoft Internet Explorer 6).&lt;/p&gt;
&lt;p&gt;I &lt;em&gt;did&lt;/em&gt;, of course, think about my job as and when required. As is my wont, I came up with a couple of suggestions to do things better in the office, but anything beyond keeping tidy, labelled piles of stuff was stymied by being stuck with a particular set of tools.&lt;/p&gt;
&lt;p&gt;This was OK. After all, I didn&#x27;t &lt;em&gt;really&lt;/em&gt; care that much. Yes, it&#x27;d be &lt;em&gt;nice&lt;/em&gt; if Mrs Smith from Glasgow could receive a response to her complaint about delayed trains a day or two sooner, &lt;i&gt;but.&lt;/i&gt;&lt;/p&gt;
&lt;hr/&gt;
&lt;p&gt;I was rudely awakened from my employmentary coasting when my office was relocated to Newcastle, a 60-minute (free) train-ride each morning and evening, on top of the twenty-minute walk. This gave me plenty of time to &lt;em&gt;read some books&lt;/em&gt; for a change, and I sped through &lt;cite&gt;The Moon Is A Harsh Mistress&lt;/cite&gt; by Robert A. Heinlein and the original &lt;cite&gt;Foundation&lt;/cite&gt; trilogy by Isaac Asimov (&lt;a href=&quot;/foundationandwhatnot&quot;&gt;in full this time&lt;/a&gt;) over the course of a couple of weeks.&lt;/p&gt;
&lt;p&gt;But co-workers and my genial manager were leaving because of the move, and &lt;a href=&quot;http://maps.google.co.uk/maps?q=newcastle%20central%20station&quot;&gt;the immediate vicinity of Newcastle Central railway station&lt;/a&gt; is no match for the lunchtime scenery afforded by York&#x27;s &lt;a href=&quot;http://maps.google.co.uk/maps?q=york%20castle%20museum&quot;&gt;River Ouse and Museum Gardens&lt;/a&gt;, especially in summer. Though I couldn&#x27;t see myself leaving, I couldn&#x27;t see myself staying there either. And so I jumped: I handed in my notice (metaphorically—I actually just told the outgoing and incoming managers when I intended to leave).&lt;/p&gt;
&lt;p&gt;Technology news was replaced by job-searching. I recall one Tuesday in Newcastle spent, by all three members of the administrative team, primarily looking for other employment.&lt;/p&gt;
&lt;p&gt;Astoundingly, it worked, and two weeks later I was staying in a hostel in Bristol about to be trained to be a charity street fundraiser.&lt;/p&gt;
&lt;p&gt;Thirty-six hours after, I found myself standing at the side of the main street in Leeds, nervously sipping at a cup of tea, trying to dilute the adrenaline.&lt;/p&gt;
&lt;p&gt;That day went unexpectedly well, propelled largely by my frequent self-reminders that I was talking to random people on the street and trying to convince them to donate to a charity, &lt;em&gt;for a living&lt;/em&gt;.&lt;/p&gt;
&lt;hr/&gt;
&lt;p&gt;Three months elapsed.&lt;/p&gt;
&lt;hr/&gt;
&lt;p&gt;My old teammate had often told me that the day&#x27;s outcome could be influenced by my expectation of what would happen. I &lt;em&gt;expected&lt;/em&gt; to come back to work and do solidly well. I expected that I knew what I was doing. My old &lt;em&gt;team-leader&lt;/em&gt; had said he firmly believed that if you wanted something enough, you&#x27;d find a way to attain it. I believed that I wanted to be a good fundraiser. The team&#x27;s coach insisted I had it in me. I deferred to his superior understanding.&lt;/p&gt;
&lt;p&gt;It was starting to become apparent that I wasn&#x27;t meeting targets. Not just the &lt;em&gt;actual&lt;/em&gt; targets, but the minimum ones too. I wasn&#x27;t earning my place on the team.&lt;/p&gt;
&lt;p&gt;This came into focus one Wednesday evening in York when, after applying every technique I could muster—level thinking, playing the long statistical game, appropriate body language, concision, knowledge, friendliness…—I found myself walking home without having signed a single person up.&lt;/p&gt;
&lt;p&gt;I realised I didn&#x27;t actually know what I was doing. I was doing a good &lt;em&gt;impression&lt;/em&gt;, much of the time, of someone who knew how to go about street fundraising, but in reality I was winging it. And not well enough. An awful day should yield no fewer than two sign-ups; the remainder of the team &lt;em&gt;had&lt;/em&gt; signed people up.&lt;/p&gt;
&lt;p&gt;I arrived largely undeterred the following morning in Newcastle, after a journey that was equally oddly familiar and strangely different. It was drizzling—not &lt;em&gt;supposed&lt;/em&gt; to affect a fundraiser&#x27;s performance, but not especially conducive to it. As it was November, there was an almighty racket accompanying a department shop&#x27;s Christmas display, rendering a decent swathe of the street useless for talking to people. I was deterred.&lt;/p&gt;
&lt;p&gt;Despite this, I signed two new donors before lunch, a decent tally for the morning session. Briefly, I convinced myself that I&#x27;d remembered how to fundraise. I spent most of the afternoon mulling over the decision to quit, safe in the knowledge that soon enough a decision would most likely be made on my behalf anyway. I even signed another person up (though I&#x27;m told he&#x27;s a serial charity-joiner).&lt;/p&gt;
&lt;p&gt;The following morning&#x27;s news headlines centred around the deepening recession: specifically around new figures for job losses, and the recession&#x27;s stifling of charitable donations. I have a wry sense of humour.&lt;/p&gt;
&lt;hr/&gt;
&lt;p&gt;Jonathan&#x27;s blog post reminded me strongly of when I left both university and fundraising. Both times, the initial spark of enthusiasm for what on paper is a pretty awesome idea had dwindled, leaving me merely going through the motions.&lt;/p&gt;
&lt;p&gt;University lectures were &lt;em&gt;not&lt;/em&gt; a chore, so the twenty-or-so hours of every week of term that they occupied weren&#x27;t sorely missed. Even spending a day in labs each week was OK. Attaining a proper quantitative understanding of physics, though, required plenty of off-timetable study—time I was loath to put in since in truth I cared little for the specifics. It showed: each week&#x27;s problem questions seemed more and more daunting, which only increased the resolve needed to actually study.&lt;/p&gt;
&lt;p&gt;Fundraising had me leaving home each day at around 07:30 and getting back at about 22:30—albeit typically due to healthy after-work socialising. (And I should point out that everything that went &lt;em&gt;with&lt;/em&gt; the job was wonderful: my teammates, and our adventures together—even running for a train back from Harrogate with one minute to spare felt like an adventure—were each uniquely brilliant).&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;I now know that I&#x27;m not capable of devoting my time to something that I&#x27;m not enthralled by.&lt;/strong&gt; It doesn&#x27;t have to be actually important—I just have to care enough to want to take control.&lt;/p&gt;
&lt;p&gt;I suppose part of it is the knowledge that someone else could be doing a better job instead of me. My demotivation in physics and fundraising alike roughly coincided with the dawning that I would be neither a brilliant cosmologist nor a legendary fundraiser respectively.&lt;/p&gt;
&lt;p&gt;I have this need to correct things and improve upon what&#x27;s there, and if I can&#x27;t make something better I tend to leave it to someone else.&lt;/p&gt;
&lt;p&gt;So I agree with Jonathan that something just being a good idea doesn&#x27;t make it a useful application of my time.&lt;/p&gt;</content></entry>
<entry><title>A-level exam results</title><id>https://gkn.me.uk/alevelexamresults</id><link href="https://gkn.me.uk/alevelexamresults" rel="alternate" type="text/html"/><published>2004-08-24T23:19:00+00:00</published><updated>2004-08-24T23:19:00+00:00</updated><summary>Rather predictably, the results of my A-level exams</summary><content type="html">
&lt;p&gt;
The &lt;abbr title=&quot;Advanced&quot;&gt;A&lt;/abbr&gt;-level exam results came out last Thursday; this is me finally bothering to write about it.
&lt;/p&gt;
&lt;p&gt;
For those living outside of the UK (or I suppose in Scotland), A-levels are the big, important exams on which universities base their admissions.
&lt;/p&gt;
&lt;p&gt;
Students apply to six universities and receive offers back from them, prior to getting their A-level results. On rare occasion, a university will make an unconditional offer of a place (i.e. “you&#x27;re in”), but most of the time, offers are conditional on receiving the grades the universities want.
&lt;/p&gt;
&lt;p&gt;
Most universities make offers based on three A-level grades. For example to get into Durham I would require an A and a B in Maths and Physics (in either order), plus a B in a third subject; or an A in both Maths and Physics, and a C in a third subject. General Studies is usually excluded from grade offers, because it&#x27;s a load of bollocks. Some universities require a minimum point total from three A-levels, where each grade is worth a certain amount; this really amounts to the same thing.
&lt;/p&gt;
&lt;p&gt;
Students then respond to these offers by selecting one first choice university, their “firm offer”, and optionally a second choice, their “insurance offer”. I only chose a firm offer - Durham. The other five universities&#x27; offers were all at the same level or higher, because Durham lowered their offer from AAB to ABB/AAC for me, something I didn&#x27;t know would happen until I&#x27;d applied to all six universities. Also, by accepting an offer as insurance, I&#x27;d be creating a contract to go to that university should they accept me.
&lt;/p&gt;
&lt;p&gt;
Besides Maths and Physics, my third subject was Religious Studies, although it&#x27;s really about philosophy, religion and ethics. The &lt;abbr title=&quot;Religious Studies&quot;&gt;RS&lt;/abbr&gt; exams took the form of written essays - quickly written essays, which caused one&#x27;s hand to develop a grudge against the rest of one&#x27;s body, particularly the brain for getting it into the exam.
&lt;/p&gt;
&lt;p&gt;
I was quite confident about Maths and Physics - I&#x27;d found the exams relatively easy. I wasn&#x27;t quite as confident about RS, but I thought I&#x27;d done enough. The second-year exams are added to the first-year exams, in which I&#x27;d got a B for RS; so I only needed a D in the second-year exams to give the C I needed overall.
&lt;/p&gt;
&lt;p&gt;
Evidently not. The first thing I saw of the results sheet was &lt;q&gt;D(d)&lt;/q&gt;. It took a bit of effort to get through to Durham - the &lt;acronym title=&quot;Universities and Colleges Admissions Service&quot;&gt;UCAS&lt;/acronym&gt; website, which would confirm that Durham hadn&#x27;t offered a place anyway, was jammed for a while. On Durham&#x27;s admissions phone line there was “no-one available to take my call”, according to a particularly dull recorded woman.
&lt;/p&gt;
&lt;p&gt;
Durham&#x27;s main phone line - the telephonic equivalent of the reception desk - &lt;em&gt;was&lt;/em&gt; available, and they were able to put me through to the admissions office... who told me I needed to contact the Physics department. They weren&#x27;t able to put me through, as the Physics department was too busy, so I was given the phone number to call. Repeatedly. To no avail. So I phoned the reception desk again, who &lt;em&gt;could&lt;/em&gt; put me through to the Physics department.
&lt;/p&gt;
&lt;p&gt;
They told me that they were full and couldn&#x27;t accept near-misses, despite my having more than enough spare &lt;abbr title=&quot;Uniform Mark Scheme&quot;&gt;UMS&lt;/abbr&gt; marks from Maths and Physics to make up for the 14 I was lacking in RS (one grade spans 60 UMS marks, except the highest and lowest), but York had some spare places going, and they&#x27;d probably take me. I phoned York and got through to the admissions office, who said my grades were plenty, but I should contact the Physics department. I got through to them quite happily, but the senior Physics admissions tutor was in a meeting, and I would have to phone back in twenty minutes.
&lt;/p&gt;
&lt;p&gt;
Twenty minutes later, the senior admissions tutor&#x27;s meeting had overran, so I&#x27;d have to phone back again in ten minutes&#x27; time. Out of her meeting, she was finally able to offer me a place at York. At this point I went to the pub - eight hours later than planned.
&lt;/p&gt;
&lt;p&gt;
The moral of the story is: if you do fourteen points better in your exams, you get to spend an extra eight hours in the pub.
&lt;/p&gt;</content></entry>
