There is no man living who isn't capable of doing more than he thinks he can do.
It has been my observation that most people get ahead during the time that others waste.
The man who thinks he can and the man who thinks he can't are both right.
One of the greatest discoveries a man makes, one of his great surprises, is to find he can do what he was afraid he couldn't do.
Vision without execution is just hallucination.
Most people spend more time and energy going around problems than in trying to solve them.
success is 99% failure
