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

If you fail, next time fail better.

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. 

If you can understand just one thing thoroughly, then you will understand everything.

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

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

Nobody said it’d be easy, they just promised it would be worth it.

99% of failures come from people who have the habit of making excuses.

Instead of finding reasons why you can't, find reasons why you can.

A book a day keeps the stupidity away.

Skills are built not born.

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

The wise person knows that no answer is also an answer

You cannot start the next chapter of your life if you keep re-reading the last one.

I think, therefore I am.
