I read an essay titled Life Is Like a Sudoku Puzzle. Typically the only Sudoku puzzles I do are in the newspaper, and it has been weeks since I’ve started one. If I mess up on one, I don’t try to figure out what I did wrong. I simply put a big x on it and throw the paper in the recycling bin. I accept defeat, but I really don’t learn anything from my mistake. But if I would look at those puzzles a little differently, I could learn a lot about life from them, just as that essay suggests.
