Puzzles are an educational opportunity, not a chance to get angry. The economist in me likes to say, no solutions, only trade offs. I have read studies that you are worse at solving puzzles and problems when you are angry. A lot of the best thinking is when we are able to make leaps between wildly different topicsand put them together. And that's hard, i think, when you're angry. But i definitely have gotten very angry many times during these two and a half years of puzzles.
