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

The easiest person to deceive is yourself.

We all make mistakes. What matters is how we choose to move forwards from them.

The temptation to quit will be the greatest when you are about to succeed

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

There are no bad mistakes in maths, only discoveries.

Mistakes have the power to turn you into something better than you were before.

You cannot escape the responsibility of tomorrow by evading it today

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

I have not failed, I've just found 10,000 ways that won't work.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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