The Two Things in your field?

The Story of the Two Things

A few years ago, I was chatting with a stranger in a bar. When I told him I was an economist, he said, “Ah. So… what are the Two Things about economics?”

“Huh?” I cleverly replied.

“You know, the Two Things. For every subject, there are really only two things you really need to know. Everything else is the application of those two things, or just not important.”

“Oh,” I said. “Okay, here are the Two Things about economics. One: Incentives matter. Two: There’s no such thing as a free lunch.”

I've always said that the Two Things about Architecture are:
1. This profession is not rocket science; if it were any easier you could teach monkeys to do it.
2. It is complex however& it isn't getting any easier.

What about you?
