If you want to succeed, double your failure rate.

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

We learn more from failure than we do from success.

Failure to prepare = preparing to fail

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

Skills are built not born.

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

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

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

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

You cannot escape the responsibility of tomorrow by evading it today

Procrastination makes easy things hard and hard things harder.

Dreams don't work unless you do.

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

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