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

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

Fall down seven times, stand up eight.

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

We all make mistakes. What matters is how we choose to move forwards from them.

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

Tough times never last, but tough people do.

Procrastination is the thief of time and the enemy of success.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

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.

I have not failed, I've just found 10,000 ways that won't work.

The master has failed more times than the beginner has even tried

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

The easiest person to deceive is yourself.
