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

There are no bad mistakes in maths, only discoveries.

Failure is not the opposite of success, it is part of the success.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

If you want to succeed, double your failure rate.

There are no shortcuts to any place worth going.

Success is not final, failure is not fatal.  It is the courage to continue that counts.

Start, struggle, fail, fix and learn. Repeat.

You cannot escape the responsibility of tomorrow by evading it today

There is no elevator to success, you have to take the stairs.

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

A book a day keeps the stupidity away.

We learn more from failure than we do from success.

Never underestimate the importance of small steps. small steps = big changes. 

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