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

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

There are no shortcuts to any place worth going.

I think, therefore I am.

Success is a journey, not a destination.

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

We all have two lives. The second begins when we realise we only have one. 

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

Patience is when you’re supposed to get mad, but you choose to understand

Don’t practice until you get it right, practice until you can’t get it wrong.

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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

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

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