Dear brain, please explain

I’m not going to bore you with the details of it, but walking up the stairs and back to my desk just now, I remembered that last night I had a dream, the upshot of which was that I made a commitment not only to myself, but to a strange David Brent type person, that I would write a symphony. According to this David Brent type person (and I promise this is the only detail with which I will regale you), anyone who is anyone has written one by the time they’re forty.

In my dream, I seemed to believe not only that I should add ‘write a symphony’ to my list of things to do, but that I had the skills to follow through.

Goodness.
