It's not that I haven't given this thing a lot of thought. I have. I thought about it then started it, then thought about it some more then scrapped what I'd started, then re-started, then thought about the re-start and scrapped that too.
At one point this afternoon I had worked my procrastinatory thinking into an absurd circular argument, which didn't help with progress at all.
On the positive side, I've learnt over the years when to abandon something and go to bed. The abridged sequence is as follows:
1. Sigh regularly while sitting at the computer for several hours: type something, sigh, delete it, type something else, sigh, delete it, type something else, sigh, and et cetera.
2. Lie on the couch because you may have better luck thinking over there.
3. As soon as you realise lying on the couch makes no discernible difference to the quality of your thought (this usually takes two to three minutes), return to the computer and do something completely unrelated to the thing you're meant to be doing.
MCL, this seems like a perfect time to show you the piccy I came across in Frankie of that great cat-print suit:


I'm sure you would look totally hot in this and I vote you dedicate your next pay to the purchase of it (or else get work to pay for it; it's clearly an office essential).
4. Having done something completely unrelated to the thing you're meant to be doing, return to the thing you're meant to be doing and say out loud: "Screw this, I'm going to bed," then go to bed.
Works for me every time.
