I think, therefore I am.

Time is your friend, impulse is your enemy.

Success is a journey, not a destination.

The journey of a thousand miles begins with one step.

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

Dreams don't work unless you do.

There are no bad mistakes in maths, only discoveries.

Everything you want is on the other side of fear

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

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

There are no shortcuts to any place worth going.

It doesn’t matter where you start, it matters how you end

If you want to succeed, double your failure rate.

Don’t hang your targets after you’re done shooting.

Procrastination is the thief of time and the enemy of success.
