Yeah, but there's always something else... a nicer house in a better location or saving enough to put your kids through college. I can see how it might be hard to walk away from a few $M more.I understand that. But if you can take your vested stocks and sell them in 4 years for millions, who cares about the stocks that are not vested yet. I sure would not.
Only people who need more will stay, the rest will retire and enjoy their lives.
