Will their definition of success remain static? The danger is that the target number and company size could keep increasing in a sort of hedonic treadmill. I'm still a believer that after a certain, not so big, amount of money, earning more money makes little difference and could even make your life worse. That's at least what I noticed in my own life progression and the life of my friends. Maybe this amount isn't 70K/year as it is often repeated, but it's certainly not 1M/year.
