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. 

No one starts out on top. You have to work your way up.

There is no elevator to success, you have to take the stairs.

The journey of a thousand miles begins with one step.

Failure to prepare = preparing to fail

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

You cannot escape the responsibility of tomorrow by evading it today

We learn more from failure than we do from success.

Success is a journey, not a destination.

Time is your friend, impulse is your enemy.

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

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

MATHS = Mistakes Allow Thinking To Happen

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

I think, therefore I am.
