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. 

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

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

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

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

Success can never happen without the journey (struggle).

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

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

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

Don’t be afraid to work hard and find out how good you can really be.

Don’t practice until you get it right, practice until you can’t get it wrong.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.
