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. 

If you fail, next time fail better.

Failure to prepare = preparing to fail

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

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

FAIL - First Attempt In Learning

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

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