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 slogan "Press On" has solved and always will solve the problems of the human race.
- Calvin Coolidge

Never give up, and luck will find you.
- Falkor (from NeverEnding Story)

Things may come to those who wait, but only the things left by those who hustle.- Abraham Lincoln

The greatest glory is not in never falling but in rising up every time we fall.
- Confucius

Never, never, never, never give up.
- Winston Churchill
