It is hard to fail, but it is worse never to have tried to succeed.
Keep your eyes on the stars, and your feet on the ground.
The only limit to our realization of tomorrow will be our doubts of today.
The only man who never makes a mistake is the man who never does anything.
Happiness lies in the joy of achievement and the thrill of creative effort.
Speak softly and carry a big stick; you will go far.
Do what you can, with what you have, where you are.
