Look back in angular

Once again, David Mitchell (this one, not these two), accidentally encapsulates my life in a few sentences:

My parents were eager for me to engage in after-school activities because they thought it would give me a more rounded personality. But the trouble with rounded personalities is that they don't tessellate. I think I get a lot more purchase on the nooks and crannies of life with my spiky one than those poor, well-adjusted sods who are sent out into a world completely unprepared for their goodwill.
