Think you are weak, think you lack what it takes, think you will lose, think you are second class - think this way and you are doomed to mediocrity.
David J. SchwartzA good idea if not acted upon produces terrible psychological pain. But a good idea acted upon brings enormous mental satisfaction. Got a good idea? Then do something about it. Use action to cure fear and gain confidence. Here's something to remember: Actions feed and strengthen confidence; inaction in all forms feeds fear. To fight fear, act. To increase fear--wait, put off, postpone.
