Non-fiction e-books that educate your potential audience on specific topics like finance, online marketing, and business are going to make you more money than fiction books. Of course, there are always exceptions and you could write the next Harry Potter book, but if you want to create some residual income opportunities quickly, I would suggest you go for what sells first!
I also disagree that every person will crave more and have to go for more. That may be a true statement for a lot, but it doesn’t have to be true and it isn’t for everyone. The other perspective of that is that most likely the people who get themselves to financially freedom, because it is no small feat, are the type of people who are extremely driven and motivated to further challenge themselves, so it’s doubtfully in their nature to stop once they actually can.
The organizing principle behind this grouping, appropriate economic units, is relatively simple: if the activities are located in the same geographic area; if the activities have similarities in the types of business; or if the activities are somehow interdependent, for instance, if they have the same customers, employees or use a single set of books for accounting.
I just wanted to say how nice it is to see such a positive exchange between strangers on the Internet. Seriously, not only was this article (list) motivating and well-drafted, the tiny little community of readers truly were a pleasant crescendo I found to be the cause of an inward smile. Thank you, everyone, and good luck to you all with your passive income efforts!! 🙂
