Your heart beat about a hundred thousand times today. It will do it again tomorrow, and it did not ask you for anything.
Now think about what a chocolate costs. A luxury bar is twenty dollars, and if you earn ten dollars an hour in the labor market, you'll have to work two hours before tax to deserve a freaking chocolate.
Two hours for a chocolate, and nothing at all for the organ keeping you alive. Everything in this book comes out of that gap, and it ends with a question about why you signed up for any of this.
