IMO: I think there is a helpful distinction to be made between leadership and management. Leadership provides purpose and inspiration. Management provides, coordination and motivation. I’m not saying one person can’t do both.

I do agree that most management books read like parenting books - but I’d add that whats more important than the method is consistency in whatever approach you believe in. I’m not sure that managers/leaders will ever do that well relying on a book or a special ‘way’ they have read. They really need to have worked this out for themselves.
