People say these things all the time, but I always wonder how you'd actually feel if you did the 3-5 year work and saved that 3-5 million you earned. My guess is with most people, you get that 3-5 million and you're going to want more. I'm not saying you specifically, but people in general.

And a clarification, I'm not thinking it'd be because you're around wealthier people which would make you want to spend more to compare to them, but rather having more security, if your passion requires more money.
