Time is really the only capital that any human being has, and the only thing he can't afford to lose.
I get my ideas from listening from within.
A good idea is never lost. Even though its originator or possessor may die, it will someday be reborn in the mind of another.
The world owes nothing to any man, but every man owes something to the world.
Accomplishing something provides the only real satisfaction in life.
Our greatest weakness lies in giving up.
