If you had an income of $150,000 a year and didn't have to work, what would you do with all the spare time?

Main question is - this Income is coming from what?

Travel with my SO,Try luxury vacations like going to Masai mara and many ultra luxurious vacations

I can tell what one won't do - vacation travel, take up a hobby, Travelling is seen as something nice because we do not get to do it often. With lot of time and money in hand there is no incentive to travel or take upna hobby. So most likely one will find job or start a business and start working. The only difference will be, this time there won't be any cribbing.

Not pay taxes

I'd put that money into a business and go back to work lol I used to think I'd chill everyday on the beach, but that's going to be an empty and boring life Even my parents want to work till 70s or more. No point retiring and chilling everyday, best to keep yourself occupied.
