I've done the "big buck" stage, but eventually even that lost its allure. I have no idea what will be "next" after the management stage.
As a financial planner, I use a financial life cycle to compare age and net worth; it helps a client see where they are compared to where they should be. I showed it to one couple and their response was, "We're just glad to see we still have more stages to go." Meaning, they weren't in the last stage. So maybe you really need to figure out what's after the management stage?
