Take a look: https://www.youtube.com/user/CountrySongTeacher/videos He provides value to customers and then leaves them hanging at the end of most videos by offering to teach a bit more extra in one of his DVDs. Every couple days, he uploads a new song for us to learn to play. I might grab his DVD just because of how much he has helped me already. How much he's making is hard to say. All he said is he is paying for his newborn from DVD sales alone, so likely more than 90% of this forum's members. This is the long term, sustainability that whitehat methods get. Great guy, great approach.
