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. 

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

The greatest glory in loving lies not in never falling, but in rising every time we fall.

We learn more from failure than we do from success.

Skills are built not born.

You cannot escape the responsibility of tomorrow by evading it today

The bad news is time flies, the good new is that you're the pilot.

There are no bad mistakes in maths, only discoveries.

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

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

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

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

There are no shortcuts to any place worth going.

Time is your friend, impulse is your enemy.

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time.
