My dear,Franklin P. Jones (1881-1960) American businessman, journalist
Bravery is not a lack of fear. In fact, while being brave you’re usually at the peak of your fear. Bravery is being the only one who knows you’re afraid. Bravery is the act of showing calm waters on top, while underneath waves roar and trash back and forth.
Franklin P. Jones
