I had this handwritten and pinned to my offfice wall. It makes me think.
Nothing in the world can take the place of persistence.
Talent will not; nothing is more common than the unsuccessful man 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.
