I found this one and it was only about $3 (if I remember correctly). I started reading it this morning at Caribou and read about 20% of the book in 20 minutes. There are only about 125 pages, and the font is big (not jumbo, but not tiny).
So far, it seems to be another one of those “common sense” books telling you what you probably already know, but might not be thinking about. If the book makes an impression on me, I might write more about it after I’ve read the rest. I’m sure it’s definitely worth the $3 I spent on it, though.
