I recently met a friend's father-in-law at a party. He seemed like a super modest guy, and then I realized he acquired a similar windfall twenty years ago. He kept working at the same company, and then jumped to a project manager role at a new company. Even after major back surgery, he kept working like an average joe (and seemed to enjoy his job). Outside of family vacations, he has only made one major purchase from his fortune - a crash-pad apartment in the Upper West Side that ended up doubling in value since the nineties. At the time, I thought he was a bit eccentric; maybe even a workaholic. Especially after reading this thread, I think he did absolutely everything correct.
