Arthur Schopenhauer

Talent hits a target no one else can hit; Genius hits a target no one else can see.”

Confucius

It is not the failure of others to appreciate your abilities that should trouble you, but rather your failure to appreciate theirs.

T.S. Eliot

Only those who risk going too far can possibly find out how far they can go.

Calvin Coolidge

Nothing in the world can take the place of persistence.
Talent will not; nothing is more common than unsuccessful men with great 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.
