But the concept of dying with 0 seems to me to be a mistake in itself, if not tell
this guy:

Do you think he is regretting not having spent more when he was young on experiences? He has had a pretty frugal life, especially compared to the wealth he has.
Buffet is one of the richests guy on earth. You won't reach him, comparing yourself with him will only lead to frustration.
Besides the fact that it seems to me a selfish concept. Using money to help others is one of the things that has given me the most satisfaction, something you can do at any age. To think that I have to die with 0 because I have to maximize my enjoyment of experiences as a young person is to think “me, me, me.”
That's not to go into whether those experiences I want to enjoy are something I need to be happy or needs created from a superficiality.
You are judging the book by its title.
Die with zero isn't selfish.
You can make charity with your money when you are alive, not dead.
You can give your money to your kids when they are young and they need money, at 30s-40s, not when you die and they are about 70s and already rich. Or even worth, your kids may die before you.
You are just wrong about the concepts of the book. Criticizing without reading .
