To this day I don't miss any experience I would like to do to save money. The main one would be to quit my 9 to 5 job but for that I don't have enough net worth yet.

Besides, I think it is a mistake to put the focus on saving.

The book is the well known YOLO but told in a different way.

It happened to me the other way around when I was younger. I spent a lot of money on bullshit because I didn't know if I was going to die tomorrow and with hindsight that money spent didn't make me any happier.
