Numbers and figures on a spreadsheet have no meaning; only thoughts have meaning. Don't let "bad" figures cripple your mind to the point that you forget that doing business is not everything. Remind yourself that what really counts in life is not what you do or how much you make, but who you are on the inside. A healthy self-esteem is the best predictor of future success. It comes from the realization that only you can decide your self-worth. A positive self-worth can boost your productivity by 100 percent.
