When I have tried and failed, I shall have failed.

My greatest fear would be the fear of failure.

But when I didn’t win the election ..

I had done my best, and that my lack of experience, not my lack of ability, was the reason for the failure.

For me, what failure was growing up was not being able to make a mistake and disappointing my parents. We are taught that it's not OK to make mistakes

A failure is a man who has blundered but is not able to cash in on the experience.

Perhaps I lost as a politician, perhaps my self-confidence played a trick on me because I did not recognize the double threat – from zealots and radicals, and from reactionaries in my immediate surroundings. Nonetheless, perestroika won. A relapse into the past is out of the question.

A failure is a man who has blundered, but is not able to cash in the experience.

Don’t be afraid to fail. The greatest failure of all is not to act when action is needed.

I learned to recognize failure.

Failure is a greater teacher than success

Failure is not falling to the ground; it is remaining there once you have fallen and the greatest failure is when you decide not to stand up again.

Defeat is not the worst of failures. Not to have tried is the true failure.

Trump's biggest failure as a political leader is that he sees the worst in people and he encourages the worst in people.
