Travel to all the places my wife and I want to go.
Buy citizenship (via investor visa) in the best developed country that fits our lifestyle and life priorities.
Buy a nice but not extravagant house.
Buy all the non-essential stuff I’ve always wanted to buy.
Hire a personal chef who will cook healthy AND delicious meals for us everyday, so I only need to cook when I actually want to.
Give a lump sum to each of my immediate family members and my wife’s mom and brother. We trust them enough to not abuse the privilege of having a billionaire family member.
