Yes, I could go a few years of doing nothing but play golf around the world and travel with my family, but then after that for the next 30 years I would need to do something structured. Maybe start up a company of some sort and be the CEO.
I'd probably just invest a ton of money into businesses that would be fun to work at, and not give a frick if they make any money.
Like putting 10+ million into a absolutely state of the art indoor/outdoor paintball facility. No expense spared. Make it literally the biggest, most up-to-date, best facility in the country.
Likely wouldn't make much money, if any off of it. But it'd be cool as shite. You could even make the prices wayyyy cheaper than any of the local competition because you aren't doing it to make a living.
Or, (stolen from the show The Lottery Changed My Life) you could get daily lessons and try to be a pro golfer. Again, you'd probably never sniff the tour, but it could be a lifelong goal that you can work towards for years/decades.
