"You will not always feel confident; sometimes your stomach will be tied up in knots and perspiration will break out all over your face. Your nervousness will be visible to other people; they may look at you curiously. Or, you may do something rash, injuring your own interests or rudely stepping on someones else's toes. Your imperfections are many--everyone is imperfect, really--and your must learn to accept this. You must understand that your blunders are not your total personality; they are just a part of you, and this is a part which you must accept to be successful. Otherwise you will dedicate your days to an avalanche of self-castigation which will leave you miserable, head bowed, a failure at almost anything you try. You must not look to others for acceptance; this is something you must give yourself."
--Maxwell Maltz, M.D., Creative Living For Today, Pocket Books, 1967
