Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

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

The temptation to quit will be the greatest when you are about to succeed

You can have results or excuses, not both

You cannot start the next chapter of your life if you keep re-reading the last one.

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

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

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

If you can understand just one thing thoroughly, then you will understand everything.

We learn more from failure than we do from success.

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

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

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

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

Knowledge is of no value unless you put it into practice.
