The greatest enemy to human potential is your comfort zone

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

You cannot escape the responsibility of tomorrow by evading it today

Time is your friend, impulse is your enemy.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

The master has failed more times than the beginner has even tried

Everything you want is on the other side of fear

Just stick with it, what seems hard now will one day be your warm up.

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

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

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

Success is the sum of small repeated efforts, day in and day out.

No one starts out on top. You have to work your way up.

The journey of a thousand miles begins with one step.
