Experience is the harvest of life, and every harvest is the result of a sowing. The experience which young people must crave is that of success in some service for which they are naturally fitted.

Leaders, true leaders, take responsibility for the success of the team and understand that they must also take responsibility for the failure.

Success comes from failure, not from memorizing the right answers.

Success depends upon previous preparation, and without such preparation, there is sure to be failure.

I was relentless, even in the face of total lack of encouragement, because much more often than you'd think, sheer persistence is the difference between success and failure.

I have tried 99 times and have failed, but on the 100th time came success.
