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

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.

There are no shortcuts to any place worth going.

The journey of a thousand miles begins with one step. 

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

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

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. 

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

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Run in the morning before your body figures out what you're doing

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

The easiest person to deceive is yourself.

Knowledge is of no value unless you put it into practice.

I think, therefore I am.
