It's the Welsh Memory Championship the weekend after next, and I've done no training for it. I'm probably going to do really really badly, like in France last year. But at least that competition put me more in the memory-training mood, and I went on to win some other competitions (as far as I can recall).
I should spend next weekend practicing for it, but then I should have spent this weekend doing that too, and I didn't. I'm still really struggling with the motivation.
