Failure to prepare = preparing to fail

The journey of a thousand miles begins with one step.

The master has failed more times than the beginner has even tried

The temptation to quit will be the greatest when you are about to succeed

The journey of a thousand miles begins with one step. 

You cannot escape the responsibility of tomorrow by evading it today

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

Pure mathematics is in its way, the poetry of logical ideas.

I think, therefore I am.

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. 

There are no bad mistakes in maths, only discoveries.

No one starts out on top. You have to work your way up.

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

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

The greatest enemy to human potential is your comfort zone
