In my experience, you can grow and retain quality people with compensation, practices, and other incentives, but you won't make them passionate about their job this way.<p>There's passion about what you do (passionate about their field, tools), and passion about what you are doing (healthcare, education, making money). These are high energy, all-in types who live their jobs. They are also few in numbers.<p>You can hire and fire based on displayed passion, but I'm not sure it can be taught. They either have it or they don't.<p>Also, don't confuse passion with work ethic, which is (probably) equally valuable, but more of a character trait that can be applied to many different things.
