A hero is no braver than an ordinary man, but he is braver five minutes longer.

There are no shortcuts to any place worth going.

Success is a journey, not a destination.

Everything you want is on the other side of fear

The greatest enemy to human potential is your comfort zone

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

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

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.
