Today the greatest single source of wealth is between your ears. - Brian Tracy

The starting point of great success in your life begins, in the simplest terms, when you discipline yourself to think and talk about only the things you want and refuse to think and talk about anything you don't want.

The ability to discipline yourself to delay gratification in the short term in order to enjoy greater rewards in the long term, is the indispensable prerequisite for success.

Anytime you stop striving to get better, you're bound to get worse.
