The One Sentence Challenge

One of the blogs I read issued the following challenge:

Physicist Richard Feynman once said that if all knowledge about physics was about to expire the one sentence he would tell the future is that "Everything is made of atoms." What one sentence would you tell the future about your own area, whether it's entrepreneurship, hedge funds, venture capital, or something else? Examples: An economist might say that "People respond to incentives." I had an engineering professor years ago who said all of that field could be reduced to "F=MA and you can't push on a rope." A couple of other good ones come immediately to mind: the GBN motto, "the future is uncertain, and yet we must act;" Bruce Sterling's "the future is a process, not a destination;" Yogi Berra's "prediction is very hard, especially about the future."

In my case, I'd probably say "everything happens for a reason" (see this post). Perhaps I suffer from confirmation bias, but I keep seeing more and more evidence in my life that it's true.

So, what would your one sentence be?
