It's fine to celebrate success but it is more important to heed the lessons of failure.
Ambition is the last refuge of the failure.
Don't be afraid to fail. Don't waste energy trying to cover up failure. Learn from your failures and go on to the next challenge. It's OK to fail. If you're not failing, you're not growing.
We have forty million reasons for failure, but not a single excuse.
One of the common failings among honorable people is a failure to appreciate how thoroughly dishonorable some other people can be, and how dangerous it is to trust them.
If you learn from defeat, you haven't really lost.
A man can fail many times, but he isn't a failure until he begins to blame somebody else.
Any fact facing us is not as important as our attitude toward it, for that determines our success or failure. The way you think about a fact may defeat you before you ever do anything about it. You are overcome by the fact because you think you are.
Many of life's failures are people who did not realize how close they were to success when they gave up.
You are capable of more than you know. Choose a goal that seems right for you and strive to be the best, however hard the path. Aim high. Behave honorably. Prepare to be alone at times, and to endure failure. Persist! The world needs all you can give.
