What I found works best is that you assume that successful managers are just lucky. Treat them like an addicted gambler and you will be successful. More of what they think made them successful, never pointing out the odds and the fact that you'd expect people to succeed on occasion with pure randomness. Treat them like they know best and never pin them down demanding a response from them, because they don't have an answer, just "work" to create an answer. Yes technical people who bubble up are an exception to this for the first few years of being manager but it doesn't last.
