The old FungFu TV show. Our hero is in a barn full of hay with other people. The bad guys have surrounded the barn and are threatening to burn it down. When asked if he was worried, he replied, " No, If they burn us out, all the worrying won't help me, and if they don't I would have worried for nothing." That is true about most things, but worrying can also start you thinking of ways to change the outcome.
