I would offer a similar answer as JTP presented. The stock market and some real estate allowed me to hit my number so I was able to retire in my early 50's. I'm by no means wealthy but I have maintained my lifestyle - I can have anything that I want but fortunately I don't want much :-). My investments include some annuities and fully paid long term care insurance so about the only thing that might screw it up is ending up on a tube :-O
I've been involved in the stock market for the past 40 years, (retail not professional). For the past 20 years, I have traded as well. Although I had a few outlandish years in 2008 and 2009 when I was net short, my goal has been to augment my income and maintain my net worth. This is a full time endeavor which I enjoy. When the market is volatile, you won't see as much of me on Stack. So why am I here?
If you come across me on Personal Finance, I answer almost every option question posed. I have utilized options for 40+ years. As JTP wrote about himself, "I enjoy the subject and enjoy helping people." In fact, helping people also helps me. Options are complex securities and working out some of the situations asked about and explaining the complexities makes me focus and helps to keep me sharp. I'd compare it to making an effort to speak a foreign language so that you retain fluency.
Another aspect of this is that although I'm full time with the stock market, I don't have to stare at quotes all day long. I determine what I want to do, set my price alarms in the morning and if they fire during the day I either take action or reset them. Often, there's a lot of time available. I read the news, read a book, and as a change of pace, I put in some time on Stack. Oddly, changing focus seems to clear my mind.
You indicated that if you could, you would never go to work and would probably spend all day on your yacht with friends drinking champagne and eating Fabergé eggs. Apart from the fact that Fabergé eggs aren't edible, that's your dream. I don't drink, I don't eat eggs and I can't afford a yacht so we're not likely to cross paths at the marina. But if you ask about something market related and I have experience in that area, we'll meet on Stack.
