Nothing in this world can take the place of persistence. Talent will not: nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not: the world is full of educated derelicts. Persistence and determination alone are omnipotent.
The great aim of education is not knowledge but action.
Human history becomes more and more a race between education and catastrophe.
For every successful actor or actress, there are countless numbers who don't make it. The name of the game is rejection. You go to an audition and you're told you're too tall or you're too Irish or your nose is not quite right. You're rejected for your education, you're rejected for this or that and it's really tough.
It is the mark of an educated mind to be able to entertain a thought without accepting it.
