Here's Ari Weinzweig's 12 "Natural Laws of Business" pulled from Zingermanns book, Being a Better Leader. I believe these are translatable to nonprofit boards and staff. I like the way these are presented and the content too! By the way, these aren't new (think Drucker and Jim Collins and....) but they are succinct, folksy even, and send clear messages.
1. an aspiring, strategically sound vision leads to greatness
2. you need to give your customers some really compelling reasons to buy from you
3. without good finance, you fail
4. people do their best work when they're part of a really great organization
5. if you want a staff to give great service, give great service to staff
6. to get great performance you need to give clear expectations and training tools
7. succesful businesses do things others know they should do, but generally don't
8. to get to greatness you've got to keep getting better, all the time
9. success means you get better problems
10. strengths lead to weaknesses
11. it takes longer to make something great happen than you think
12. great organizations are appreciative and the people in them have more fun
