The greatest enemy to human potential is your comfort zone

Mistakes have the power to turn you into something better than you were before.

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

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

Instead of finding reasons why you can't, find reasons why you can.

You can be shown the path, but only you can make the first step.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

You can have results or excuses, not both

I think, therefore I am.

Don’t practice until you get it right, practice until you can’t get it wrong.

Fall down seven times, stand up eight.

Pure mathematics is in its way, the poetry of logical ideas.

Shoot for the moon and even if you miss you’ll land among the stars/

We all have two lives. The second begins when we realise we only have one. 

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