Recently i read a book called die with zero, which made me rethink a lot of my ideas of accumulation of money
You don't have offspring, do you? The Rothschilds are very happy with you believing that idea, I wouldn't be surprised if they had paid the author underhand.
I don't care about Rothschild or any other billionaire. I just want to live my life the best way possible, I don't want to change the world.
I know money grows over time,
but Money has a declining utility over you age.
You can save millions until you are 75 , missing many good experiences and spending then millions in better hospitals when you are 80s 90s (because you won't be able to travel at that age) Or just left all your sacrifice over the years for your kids (which might not even need your money when you die)
Spending money in experiences which will make you a happier person and with more culture is a good way to spend money, imo.
