Don’t be afraid to work hard and find out how good you can really be.

Don’t hang your targets after you’re done shooting.

Failure is not the opposite of success, it is part of the success.

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

The wise person knows that no answer is also an answer

Start, struggle, fail, fix and learn. Repeat.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

We learn more from failure than we do from success.

The road to success is like a staircase. If you want to succeed, double your failure rate

I think, therefore I am.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

Do what you have always done and you will always be what you have always been

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.
