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. 

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.

I can is 100 times more important than IQ.

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

You can be shown the path, but only you can make the first step.

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

The easiest person to deceive is yourself.

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

Dreams don't work unless you do.

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

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

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

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

If you fail, next time fail better.
