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

If you want to succeed, double your failure rate.

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

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

Your attitude is everything. Pick a good one.

The power of reflection is the most powerful skill you’ll learn.

Dreams don't work unless you do.

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.

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

There are no bad mistakes in maths, only discoveries.

Success can never happen without the journey (struggle).

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

It always seems impossible until it's done.

You can hire a tutor but you can't hire someone to practice for you.
