Failure is NOT your destiny. Failure is the key to success.

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

The greatest enemy to human potential is your comfort zone

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

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

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

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

Tomorrow is worth more than yesterday but less than today.

Your attitude is everything. Pick a good one.

Everything you want is on the other side of fear

Don’t be afraid to work hard and find out how good you can really be.

You cannot escape the responsibility of tomorrow by evading it today

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

Failure is not the opposite of success, it is part of the success.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.
