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

I think, therefore I am.

Fall down seven times, stand up eight.

Instead of finding reasons why you can't, find reasons why you can.

99% of genius comes from hard work, the remaining 1% comes from innate talent

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

Don't fear failure, fear being in the same exact same place next year as you are now.

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

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

Everything you want is on the other side of fear

You can have results or excuses, not both

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

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

We learn more from failure than we do from success.

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