the top answer is really well done, but lacks the gem from the second answer: "One of the major rookie mistakes I have made and see many others make is the assumption that human motivation is tied to economic outcomes"

put another way - you might have a personal ambition to have a title like "VP of Engineering" or make $500k a year, but most others don't. so if you project your motivations / world view on those who work for you, you will have a bad time building a great team with a great culture. knowing what your people value is really important and will help you get the best work from your team.
