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

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

The journey of a thousand miles begins with one step. 

In order to become better than anybody else you must first become better than yourself.

Success is a journey, not a destination.

I think, therefore I am.

If you fail, next time fail better.

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

Your limitation - its only your imagination.

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

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

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

Success is not final, failure is not fatal.  It is the courage to continue that counts.

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

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