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

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

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. 

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

You can be shown the path, but only you can make the first step.

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.

Everything you want is on the other side of fear

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

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

FAIL - First Attempt In Learning

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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

You cannot start the next chapter of your life if you keep re-reading the last one.

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

I can is 100 times more important than IQ.
