The famous War-Time Prime Minister and British Leader Sir Winston Churchill said,

Courage is what it takes to stand up and speak; courage is also what it takes to sit down and listen.

When I feel compelled to speak, it is sometimes tougher to stay silent than is to speak my mind, and other times, it is more righteous to speak than let be overshadowed in silence. For this reason, it is not in speaking or listening that courage is found, but in the decisive action of doing one lest the other.

A quick side note of trivia: Churchill proposed marriage to the Academy Award-Winning Actress Ethel Barrymore, she declined.
I say she had courage.
