Nothing in the 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 alone will not; the world is full of educated derelicts.
Persistence and determination alone are omnipotent.
A tattered copy of this poem hung in my childhood home where I read it daily. It still inspires me to do my best and never give up.
