Success is not final, failure is not fatal: it is the courage to continue that counts.

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

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

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

The keys to success are patience, persistence, and obsession.

It's fine to celebrate success, but it is more important to heed the lessons of failure.
