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

There are no bad mistakes in maths, only discoveries.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Success is the sum of small repeated efforts, day in and day out.

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

You cannot escape the responsibility of tomorrow by evading it today

You can hire a tutor but you can't hire someone to practice for you.

Practice like you’ve never won. Perform like you’ve never lost.

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

If you fail, next time fail better.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

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. 

99% of failures come from people who have the habit of making excuses.

A hero is no braver than an ordinary man, but he is braver five minutes longer.
