Charles de Gaulle
Deliberation is the work of many men. Action, of one alone.
Ralph Waldo Emerson
Do not be too timid and squeamish about your actions. All life is an experiment.
Alfred A. Montapert
Do not confuse motion and progress. A rocking horse keeps moving but does not make any progress.
Do not let what you cannot do interfere with what you can do.
Do what you can, with what you have, where you are.
Doing is a quantum leap from imagining. Thinking about swimming isn't much like actually getting in the water.
Don't be afraid your life will end; be afraid that it will never begin.
Don't mistake activity for achievement.
Frank C. Bucaro
Don't wait for someone to take you under their wing. Find a good wing and climb up underneath it.
Don't wait. The time will never be just right.
