The journey of a thousand miles begins with one step. 

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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

I think, therefore I am.

If you fail, next time fail better.

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

Try and do one thing each day that you would really rather not do.

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

The greatest mistake we make is living in constant fear that we will make one.

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

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

Time is your friend, impulse is your enemy.

Practice like you’ve never won. Perform like you’ve never lost.

It is never too late to turn an unproductive day into a productive one.

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