Speak softly and carry a big stick; you will go far.
The only man who never makes a mistake is the man who never does anything.
The only limit to our realization of tomorrow will be our doubts of today.
Do what you can, with what you have, where you are.
Happiness lies in the joy of achievement and the thrill of creative effort.
When you're at the end of your rope, tie a knot and hold on.
Keep your eyes on the stars, and your feet on the ground.
No one cares how much you know, until they know how much you care.
Do what you feel in your heart to be right – for you'll be criticized anyway.
It is hard to fail, but it is worse never to have tried to succeed.
