Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

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

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

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

The power of reflection is the most powerful skill you’ll learn.

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.

Don’t compare yourself to others. Compare yourself to the person you were yesterday.
