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

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

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

A hero is no braver than an ordinary man, but he is braver five minutes longer.

Your limitation - its only your imagination.

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

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

Nobody said it’d be easy, they just promised it would be worth it.

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

The greatest glory in loving lies not in never falling, but in rising every time we fall.

If you can understand just one thing thoroughly, then you will understand everything.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

The road to success is like a staircase. If you want to succeed, double your failure rate

Practice like you’ve never won. Perform like you’ve never lost.
