We've got to search back to our last known safe landmark. I can't say exactly where, but I think it's back there at the start of the Industrial Revolution, we began applying energy in vast amounts to tools with which we began tearing the environment apart.

Set your sights high, the higher the better. Expect the most wonderful things to happen, not in the future but right now. Realize that nothing is too good. Allow absolutely nothing to hamper you or hold you up in any way.
