Failure to prepare = preparing to fail

Hard work beats talent when talent doesn't work hard.

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

It always seems impossible until it's done.

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

I think, therefore I am.

Never underestimate the importance of small steps. small steps = big changes. 

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

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

You're not in competition with anyone but yourself. Outdo your past, not other people.

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

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

The power of reflection is the most powerful skill you’ll learn.

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

We are all maths people : step 1 - do maths and step 2 - be a person.
