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

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

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

You can have results or excuses, not both

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.

It is never too late to become what you might have been

The master has failed more times than the beginner has even tried

Try and do one thing each day that you would really rather not do.

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

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

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

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.

If you want to succeed, double your failure rate.

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

Failure to prepare = preparing to fail
