The journey of a thousand miles begins with one step. 

There is no elevator to success, you have to take the stairs.

The greatest enemy to human potential is your comfort zone

We learn more from failure than we do from success.

I can is 100 times more important than IQ.

Success is a journey, not a destination.

You're not in competition with anyone but yourself. Outdo your past, not other people.

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

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

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

Tomorrow is worth more than yesterday but less than today.

It is never too late to become what you might have been

There are no bad mistakes in maths, only discoveries.

Do what you have always done and you will always be what you have always been

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.
