It is never too late to become what you might have been

Time is your friend, impulse is your enemy.

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

Everything you want is on the other side of fear

Failure to prepare = preparing to fail

Fall down seven times, stand up eight.

Skills are built not born.

Dreams don't work unless you do.

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

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

It is never too late to turn an unproductive day into a productive one.

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

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

I have not failed, I've just found 10,000 ways that won't work.
