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

Don’t be afraid to work hard and find out how good you can really be.

Don’t hang your targets after you’re done shooting.

Failure to prepare = preparing to fail

Shoot for the moon and even if you miss you’ll land among the stars/

If you fail, next time fail better.

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

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

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. 

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.

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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.

Just stick with it, what seems hard now will one day be your warm up.
