I watched an episode of Shark Tank once where I was introduced to Major Robert Dyer. Major Dyer was pitching a new energy drink called The Ruck Pack Energy Drink. It’s not like the world needs another energy drink, but he was able to convince both Kevin O’Leary and Robert Herjevic, two of the investors on the show, to give him $150k in exchange for 20 percent of the company.
Of course, you can make honst money in Internet info-products, or affiliate marketing, or other such areas where people tend to get drawn to "passive income" fantasies. But, to make real money over the sustainable long-haul, you must treat these like any other business. In other words, you must provide real value to real customers with a real need.
Nobody gets early FI investing in bonds, CD’s, or even stocks unless they make a huge income or are extremely frugal or a combination of both. Paper assets just don’t provide enough returns. Business income can be great but it is typically not as semi-passive as I would like and there is a relatively high failure rate. That is if you can monetize an ideal to begin with. RE investing needs to be higher ranked IMO as a way that the “average guy” can become FI.
Ebooks are one of my favorite sources of passive income. Now, you can do this the simple way and just publish it on Amazon's KDP. Or, you can go all out and build yourself a book funnel. Book funnels are powerful, but they won't be fully passive. For example, if you do a free-plus-shipping offer for your ebook (converting it into a physical book), you'll need to create some one-time offers (i.e. extra training) and up-sells (i.e. an audiobook). But, a book funnel can be very powerful.
Have you always wanted to own your own business? You could start a side business while you work a full-time or part-time job. For example, if you're a graphic or web designer, you could start your own graphic or web design business on the side. If you like to make jewelry, you could sell at craft fairs and online. Starting a business may be daunting, but if you believe in you and your work, you could earn a decent living, maybe even quit your day job. Search out those who are doing what you want to do and interview them. Find out the mistakes they made and ask for guidance.
One of the great parts about the online world is that a website and its domain name is like real estate - It can go up in value over time. In fact, sometimes just the domain name without the developed business can be worth quite a lot to some people. Of course, like almost anything mentioned here, the necessary know-how is required. If you’re willing to put some time into it, then you can earn a nice online income. So far I sold 4 domain names with an average price tag of a couple of thousand dollars. Nice income, considering I bought each domain for around $10….If this income stream interests you, check out flippa.com - It’s one of the best marketplaces I know for selling websites or domain names.
