Once I get on a puzzle, I can't get off. If my mother's friend had said, "Never mind, it's too much work," I'd have blown my top, because I want to beat this damn thing, as long as I've gone this far. I can't just leave it after I've found out so much about it. I have to keep going to find out ultimately what is the matter with it in the end.

I also noticed that as you go to sleep the ideas continue, but they become less and less logically interconnected. You don't notice that they're not logically connected until you ask yourself, "What made me think of that?" and you try to work your way back, and often you can't remember what the hell did make you think of that!
