"The people you choose must (a) make you think smarter and (b) put lots of solutions on the table in a short amount of time. I don't care who it is, the janitor or the intern or one of your most trusted lieutenants: If they can help you do that, they should be at the table." Believe me, you don't want to be at a company where there is more candor in the hallways than in the rooms where fundamental ideas or matters of policy are being hashed out. The best inoculation against this fate? Seek out people who are willing to level with you, and when you find them, hold them close."
