So that morning in 1962 I told myself: Let everyone else call your idea crazy . . . just keep going. Don’t stop. Don’t even think about stopping until you get there, and don’t give much thought to where “there” is. Whatever comes, just don’t stop.

Success is not sustainable if it is defined by how big you become or by growth for growth's sake. Success is very shallow if it doesn't have emotional meaning.

你的能量水平越高，你的身体就越高效。你的身体越高效，你感觉越好，你就越会利用你的才能产生出色的结果。
