The only certain means of success is to render more and better service than is expected of you, no matter what the task may be. This is a habit followed by all successful people since the beginning of time. Therefore I saith the surest way to doom yourself to mediocrity is to perform only the work for which you are paid.
Og MandinoRemind thyself, in the darkest moments, that every failure is only a step toward success, every detection of what is false directs you toward what is true, every trial exhausts some tempting form of error, and every adversity will only hide, for a time, your path to peace and fulfillment.
