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. 

We learn more from failure than we do from success.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

Procrastination makes easy things hard and hard things harder.

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

Skills are built not born.

You're not in competition with anyone but yourself. Outdo your past, not other people.

Fall down seven times, stand up eight.

We all have two lives. The second begins when we realise we only have one. 

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

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

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.

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