I want to echo the words of John Calvin Coolidge who said,
"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.
The slogan 'press on' has solved and always will solve the problems of the human race."
Cheers!
