Don't Give Up
Some things are hard to improve upon, as is this advice from Calvin Coolidge.
Every truly successful person history shares this characteristic.

Press On

Nothing in the world can
take the place of

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.
