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

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

Success is a journey, not a destination.

Everything you want is on the other side of fear

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

The greatest enemy to human potential is your comfort zone

Pure mathematics is in its way, the poetry of logical ideas.

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

If you want to succeed, double your failure rate.

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