Courage is the most important of all the virtues, because without courage you can’t practice any other virtue consistently. You can practice any virtue erratically, but nothing consistently without courage.
Courage is not simply one of the virtues, but the form of every virtue at the testing point.
C. S. Lewis
He who is not courageous enough to take risks will accomplish nothing in life.
Efforts and courage are not enough without purpose and direction.
John F. Kennedy
