It's easy! Anybody can do it.

If this current, conventional 'world' is not quite up to the job of providing for nine billion people in a scant forty years, this strongly suggests we need change. Which, if you think about it, is awesome! That is, change happens whether we like it or not. The truly excellent part is realizing we have--and we've always had that--the ability to shape that change. That is, you have the ability to shape that change. We all have that in us.
It starts by believing you can.

When I am not developing my life as the unconventional consultant, when I am not building houses (a story for another day here), I am developing a world wide organization I call "Transform the World". While on the surface this seems like a pretty tall order ("You're going to what? Transform what?" "The World?" "Are you nuts?") it isn't at all. It's easy. Anybody can do it. Including you. You start by transforming yourself. Admittedly, that is the hard part, as it is a life's process.
But when compared with all the many trivial pursuits we can take in life, if you really look at the process of transforming you, you'll find it is one of the highest rewards for yourself. You get the very best you can be, and the world gets transformed in the bargain.

It's easy--ANYbody can do it. Including you.
