And I have to say, it's been a pretty successful week all round. I've got lots of clever stuff done at work, I've refrained entirely from eating anything between meals, despite Colin bringing a box of doughnuts into the office today, I've done a proper memory training session every evening, and I've watched every episode of Bagpuss!
Now it's a three-day weekend, and I'm going to win lots of games of othello, memorise lots of numbers (both decimal and binary) and cards, and catch up with lots of friends who I've been sort of neglecting lately.
Or else stay in bed all weekend doing nothing. We'll see how I feel.
