The only way to do great work is to love what you do.
Success is stumbling from failure to failure with no loss of enthusiasm.
Speak softly and carry a big stick; you will go far.
Keep your eyes on the stars, and your feet on the ground.
It does not matter how slowly you go as long as you do not stop.
It is hard to fail, but it is worse never to have tried to succeed.
Do what you can, with what you have, where you are.
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.
The best way to predict the future is to create it.
