I wish you the best. It's hard to fully retire unless you are just filthy rich, which I am not. But I expect those who are well-off are involved in businesses and other enterprises from which they may not want to walk away. The extra time is can be a burden, I expect, unless you have enough money to travel, etc.
I am semi-retired. I spend most of my time writing. I am a Master Electrician and I provide my license for a company that installs backup generators for residences and businesses. They pay me for the use of my license and that gives me an extra income stream. My books haven't made the NYT best sellers list yet but I make a little money from sales. When the company installs a generator, I have to be on the job to supervise, and I get paid for that. My wife and I both draw Social Security, and occasionally, I go do some electrical work for someone and make some extra cash.
When you retire, just make sure you have something to occupy your time and your mind. Otherwise the boredom may take a toll on you.
