>No mature, responsible adult grounds his life or his actions in his passions.
I somehow keep it together, as a sample size of one.
Don't see much point in playing word games. You can call it "obsession" or "investment" or simply "greed". The point is they have a strong intrinsic factor that keeps them around and makes them strongly opinionated on how to best make money.
>It is better to say "dedicated to the company and its mission".
that implies they won't take the next golden parachute 12 months out if they fail, as opposed to trying their best to keep the company they "are dedicated to" afloat. I think that gives too much credit. Wheras like you say, passion can quickly burn out.
And their feelings on the company is very relevant to how much of a damn they give. They can say "I quit" and never work a day in their lives again, they don't have any "dedication" to working. You can very much tell in many cases when leadership stopped caring about the company and are looking out the door.
