I like to play
Web Sudoku to clear my mind. I've gotten really good at the game and in this particular version, when you check your progress it tells you "Everything is OK." There's nothing like something telling you that everything is OK to make you feel at least marginally better. Last night I started playing a game to get my brain back in gear for composing, but I started making really stupid mistakes and ended up with conflicting results. And the game told me that everything wasn't ok. "Something is not quite right in 2 of the cells!" And that made me feel worse than I did before. *sigh*
