Thanks! I thought exactly the same. "A book costs 10 hours" ?? oh come on, no, 10 hours is the amount of time you can have the privilege of "wasting" while relaxing in a confy sofa with a cup of tea, while being entertained or learning, _thanks_ to that book. It't not a cost. It's a gift.
Some people need to learn how to relax, forget about maximizing value of everything, and just enjoy the act of doing nothing.
