There is no elevator to success, you have to take the stairs.

Failure is NOT your destiny. Failure is the key to success.

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

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

You can have results or excuses, not both

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

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

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

Whenever you find yourself doubting how far you can go, just remember how far you have come.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

Life is full of opportunities. With every opportunity that is missed, another one is born.

Pure mathematics is in its way, the poetry of logical ideas.

Dreams don't work unless you do.

Failure to prepare = preparing to fail
