Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

Failure to prepare = preparing to fail

The road to success is like a staircase. If you want to succeed, double your failure rate

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

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. 

Dreams don't work unless you do.

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

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

Knowledge is of no value unless you put it into practice.

Success can never happen without the journey (struggle).
