I mean, you have to be able - you have to have made the commitment within yourself to do whatever it takes to get the job done and to try to inspire other people to do it, because obviously the first rule is you can't do it by yourself.

Your only competitors are your past achievements.

So my message is in whichever realm, be it going into space or going into the deep sea, you have to balance the yin and yang of caution and boldness, risk aversion and risk taking, fear and fearlessness. No great accomplishment takes place, whether it be a movie or a deep ocean expedition, or a space mission, without a kind of dynamic equipoise between the two. Luck is not a factor. Hope is not a strategy. Fear is not an option.
