A man has made at least a start on discovering the meaning of human life when he plants shade trees under which he knows full well he will never sit. Outside noisy, inside empty. If you're alive, it isn't. Sow a habit and you reap a character. Mistakes are part of the dues one pays for a full life.
Failure is an event, never a person.
You've failed many times, although you don't remember. You fell down the first time you tried to walk. You almost drowned the first time you tried to swim. . . . Don't worry about failure. . . . The scoreboard can't make you a loser.
