The Iron Laws

1. You get more of what you reward and less of what you punish.
2. Money and power will always find each other.
3. If everything is a priority, nothing is a priority.
4. The less you know about something, the easier it looks.
5. You aren’t free unless you are free to be wrong.
6. Me today, you tomorrow.
7. Foreseeable consequences are not unintended.

I might restate #7 a bit, but these are pretty good. Thanks to RC Dean.
