Your words have power—especially over you. Harping about your problems always makes you feel worse, not better. If something goes wrong, don’t waste time complaining. Put that mental energy into making the situation better. (Unless you want to whine about it forever, eventually you’ll have to make it better.) And do the same with your friends or colleagues. Don’t just serve as a shoulder they can cry on. Friends don’t let friends whine; friends help friends make their lives better too.
