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 will not;
the world is full of educated derelicts.

Persistence and determination alone
are omnipotent.

The slogan 'Press On' has solved
and will always solve
the problems of the human race.

Calvin Coolidge
