Chess cause and effect

Chess helps one separate "cause and effect" from extraneous information.  Even if you have a tendency to place your queen in the worst possible place in a game, when you see the result you have a tendency to be a little more careful in life, if not in chess!  That's how chess helps one live better even if one never really gets much better at chess.  Lose a game?  So what?  Lose your life?  A little more important.  Chess teaches that too.  And finally, chess teaches that you can still win a game after you've thrown your queen away in a stupid move. That may be chess most important contribution to all of us.
