The greatest enemy to human potential is your comfort zone

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

Fall down seven times, stand up eight.

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

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

Dreams don't work unless you do.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

The journey of a thousand miles begins with one step. 

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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.

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

I can is 100 times more important than IQ.

The journey of a thousand miles begins with one step.

I think, therefore I am.

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