Obviously, the goal is to keep people in positions they are best and happiest at. But that isn't always an option and the people who are admired the most are those that have versatility, positive attitudes, good learning abilities, are team players, and put the love of winning with their team ahead of what makes them comfortable or happy in the moment.
I've seen lots of talented people who are focused on only what they love or are comfortable doing, even if the team needs something else. That never ends well.
On the other hand, I've never seen anyone who consistently did whatever it took for the team to win, including developing new capabilities, who wasn't wealthy in all aspects of their life.
