After fulfilling your goals and your life becomes boring that's on you, there are 100s of places around the world I want to visit before I leave this world behind, there are many sightseeing I want to see, nothing beats having the time to go on adventures and travel around the world, instead of making it all and sitting your ass down in your home, that's a boring life, with money you life shouldn't be boring, there are too many things you can do to make your day a good one.
You are right and I have seen some celebs complaining about what OP is saying too. But as you said, there should be many meaningful things you had wanted to do when you didn't have the means (money) to do or visit those places and doing the things now you have money and you end up still being bored, then money wasn't the person problem, to begin with. I can't wait to get to that point I can get up and go by myself or with family and do things I/we wanted to cos we can afford it.
