The greatest enemy to human potential is your comfort zone

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

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

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