It doesn’t matter where you start, it matters how you end

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. 

The journey of a thousand miles begins with one step.

There are no bad mistakes in maths, only discoveries.

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

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

Fall down seven times, stand up eight.

I think, therefore I am.

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

Whenever you find yourself doubting how far you can go, just remember how far you have come.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

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

Try and do one thing each day that you would really rather not do.

Never underestimate the importance of small steps. small steps = big changes.
