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

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

The temptation to quit will be the greatest when you are about to succeed

Hard work - a two way street where you get exactly what you put in.

Failure is not the opposite of success, it is part of the success.

Run in the morning before your body figures out what you're doing

Dreams don't work unless you do.

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

I think, therefore I am.

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

Mistakes have the power to turn you into something better than you were before.

A book a day keeps the stupidity away.

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

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