Failure comes from ego, greed, envy, fear, imitation. I have success not because I am smart, but because I am rational.

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

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.

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

If you don't give people a chance to fail... you won't innovate... if you wanna be an innovative company allow people to make mistakes.

Many of life's failures are people who did not realize how close they were to success when they gave up.
