David J. Schwartz
Your success is determined not by the size of your brain or the extent of your talent, but by the sheer size of your thinking and your belief in what is possible.
Action cures fear and builds confidence, whereas hesitation and postponement only magnify anxiety.
You must vaccinate yourself against excusitis, the failure disease that causes people to rationalize their lack of progress through complaints about age, health, intelligence, or luck.
The words you use create mental images, so always choose bright, positive language to describe yourself, other people, and your future.
