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

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

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

I can is 100 times more important than IQ.

The journey of a thousand miles begins with one step. 

Instead of finding reasons why you can't, find reasons why you can.

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

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

It is never too late to become what you might have 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. 

Your attitude is everything. Pick a good one.

Start, struggle, fail, fix and learn. Repeat.

The greatest mistake we make is living in constant fear that we will make one.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

In order to become better than anybody else you must first become better than yourself.
