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

The greatest enemy to human potential is your comfort zone

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

I have not failed, I've just found 10,000 ways that won't work.

Failure to prepare = preparing to fail

I can is 100 times more important than IQ.

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

Life is full of opportunities. With every opportunity that is missed, another one is born.

Patience is when you’re supposed to get mad, but you choose to understand

The bad news is time flies, the good new is that you're the pilot.

You can have results or excuses, not both

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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

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