QUOTE

"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.
Persistance and Determination alone are omnipotent.
The slogan "Press On" has solved and will always solve the problems of the Human Race."

Calvin Coolidge
Former USA President
(1923/1929)

Twenty years from now you will be more disappointed by the things you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the Trade Winds in your sails. Explore. Dream. Discover."
- Mark Twain

"Everyone starts off with a bag full of luck and an empty bag of experience.
The trick is to fill the experience bag before the luck bag is empty."
- Raul
