We spend a lot of time thinking and worrying about things that never even happen. My mom used to say, “Don’t be such a worry wart.” When I was a child, hearing this would put an image of a grotesque, shriveled up growth on some part of the body that was a nag to remove. I must admit that even if I did not have a clue about what she meant by that-I was thoroughly inclined to stop doing, thinking or speaking the way I was before she said that-just by sheer adverse reaction to my thought of a wart.
