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. 

I think, therefore I am.

Dreams don't work unless you do.

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

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

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

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

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

It is never too late to turn an unproductive day into a productive one.

You can have results or excuses, not both

Success is a journey, not a destination.

Mistakes have the power to turn you into something better than you were before.

FAIL - First Attempt In Learning

Hard work - a two way street where you get exactly what you put in.

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