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

Time is your friend, impulse is your enemy.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day.

He who has begun his task is half-way done. Have the courage to begin!

I think, therefore I am.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

Failure is NOT your destiny. Failure is the key to success.

Mistakes have the power to turn you into something better than you were before.

In order to become better than anybody else you must first become better than yourself.

Fall down seven times, stand up eight.
