I have not, but I know a friend who did this for a while directly out of high school. I've never read the book, but most of these types of books say "create passive income using ____________" he made a pdf and charged 15 bucks for it. Sold it on his own website and made ~$1500-2000 a month. the money he used to live and built some other not so successful websites. We were straight out of highschool though so this was enough money to live on and he didnt TOUCH the webpage for like 2 years steady income. Sometimes people just get lucky I guess.
