If you can discipline yourself to do what you should do, your success is virtually guaranteed. Self-discipline requires self-mastery, self-control, self-responsibility, and self-direction.
Your greatest asset can be your willingness to persevere longer than anyone else. In fact, your persistence is a true measure of your belief in yourself and your ability to success.
Successful people are decisive and they try far more things than other people do. If you try far more different ways to be successful, the odds are that you will eventually find the right way for you, at the right time.
