Great post Jim. While it is convenient to lump the entire dividend income as one passive stream, in reality, it is several. If you have 30 companies across 10 major industry sectors, each paying you dividends, then you can consider having 30 streams or at least 10 passive streams, from each of the diverse industry sectors. I find this more diverse than relying on rental income from one investment property tied to one location and one good tenant. Your point about website is absolutely valid – will be great to have Ten Factorial Rocks worth 7 figures in less than 5 years as you have done!
When withdrawing money to live on, I don’t care how many stock shares I own or what the dividends are – I care about how much MONEY I’m able to safely withdraw from my total portfolio without running out before I die. A lot of academics have analyzed total market returns based on indices and done Monte Carlo simulations of portfolios with various asset allocations, and have come up with percentages that you can have reasonable statistical confidence of being safe.
As long as it’s something I believe it and support, it’s a win – win. Companies I’ve been approached by in the last two years include John Hancock, Credit Karma, Discover, Capital One, MasterCard, and GM, just to name a few. It’s been so fun helping these awesome companies create their own marketing plans, whether through video or other online media.

If you’ve ever thought to yourself, “I wish there was a product that did this,” then invent it! Create a product, medical or otherwise, and sell it as a company or get royalties for it. It’s not impossible to figure out, I have many friends who have taken a concept to market. Don’t overlook an invention as a fantastic means of attaining passive income.
Wouldn’t it be nice to earn money while not working? That money is called residual, or recurring, income. It's what can happen after you put a lot of time, effort and sometimes money into a job to continue to get paid for the work months or years after it's done. (Salary jobs are part of linear income. This income is directly related to the number of hours you work. If you work 40 hours, you get paid for 40 hours of work.) Once you set up your business to earn residual income, you continue to make money while doing other things – maybe even starting a new business to generate more residual income!
Recently, the residual income (RI) model has become very popular in valuation because it purports to measure "value added" by explicitly taking into account the cost for capital in the income statement. Some proponents of the residual income approach have even suggested that the RI model is superior to the discounted cash flow (DCF) method and consequently, the DCF model should be abandoned in favor of the RI model. The residual income model is seductive because it purports to provide assessments of performance at any given point in time. The claim that the RI model is superior to the DCF model in valuation is puzzling because the RI model is simply an interesting algebraic rearrangement of the DCF model. Since the same information is used in both models, it is not unexpected that both models should give the same valuation results.
But that’s more like a fairytale. You’ll have to put in some effort to continue receiving residual income on the business you started. Talking to your managers and representatives will help them be more productive and run your business better. Marketing your online sales through social media and your network will help earn you more money. But you just won’t have to work at it as your full time job. Think of it as a part time job that can potentially bring in full time pay.
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.

Still, you can expect to make a few hundred dollars to a few thousands dollars per month with one ebook depending on how good it is. The more value that you can add through that ebook, the more likely it’s going to be successful. Focus on value here and not on how to do the least amount of work for the greatest return if you actually want to succeed with this.

Investing in coins and collectibles: Buffalo nickels and Spiderman comic books are good examples of coins and collectibles that can rise in value, and thus offer opportunity for passive income investors. You'll need to get up to speed on the value of any coin or collectible under consideration, but once you do so, you're on the way to price appreciation on a commodity you'll be paying a lower price to buy, and will garner a higher price when you sell.
Not only that but in almost all other cases there is the illusion of influence, which is itself a psychological and emotional cost. If you invest in a business that your friend or family member is running, you can see how things can get messy. You have thoughts on how things should be done, they have competing thoughts, if things aren't going well… we know how this story goes.
Reality Two: You have a limited amount of time on this planet to implement your business plans and strategies, while also trying to balance the needs of family, health, spirituality, recreation, relationships, and much more. Do you really want to spend your limited time nursing more than one stream of income? Happiness has more to do with balancing life than making tons of money.

Creating multiple streams of income does not mean get a second job to supplement your current income. A second job does not provide you with the flexibility and freedom to increase your income. In fact, it can hurt you when you think about it. You are trading time for money and in the long run, you lose. Instead, create something that will allow you to give yourself a pay raise when you need and want it. 
Residual income valuation (RIV) which is also known as residual income method or residual income model (RIM) is an approach to or method of equity valuation which properly accounts for the cost of equity capital. The word ‘residual’ refers to any opportunity costs in excess which is measured as compared to the book value of the shareholders’ equity and the income that a firm generates after accounting for the true cost of capital is then the residual income. This approach is largely similar to the MVA/EVA based approach having similar advantages and logic.
You can source products through wholesale sites like Alibaba, or you can go directly to manufacturers with your designs and build things from scratch, although I wouldn’t recommend it unless you have experience in the manufacturing industry. For importing your items, you could either fly directly to another company to view production and product lineups, or you could simply turn to Alibaba to assist with that.

A few people who started their own YouTube channel when the video-sharing site was in its nascent stage are now millionaires. Now that YouTube has become immensely popular with hordes of people running their own channels, making a million dollars is considerably more difficult, but earning a respectable sum of money is still possible. As always, you'll need to find a niche that isn't yet saturated and focus on making engaging videos around it. Once you start raking up views and subscriptions, the money will start flowing in with minimum effort on your part.

Residual income is when you continue to get paid after the work is done. This includes royalties from books, movies, or songs and also income that comes from real estate or business investments where you don’t actually have to be present to earn it. For example, Bill Gates is still making a residual income from Microsoft even though he isn’t working there anymore.
