Hard work - a two way street where you get exactly what you put in.

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

Dreams don't work unless you do.

Time is your friend, impulse is your enemy.

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

There are no bad mistakes in maths, only discoveries.

You can have results or excuses, not both

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. 

A book a day keeps the stupidity away.

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

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

Don't fear failure, fear being in the same exact same place next year as you are now.

I think, therefore I am.

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

Whenever you find yourself doubting how far you can go, just remember how far you have come.
