If you know anything well, a place, how to fix something, how to make something, how to do something, you can write a guide for it. You can sell your guide as an e-book, offer it as a download for a fee on your site or reach out to bloggers with similar content and ask if they will offer it as a paid download on their website (for a price of course).
If you’re worried about launching a new product, and think you might need some feedback to make it really good, Flynn recommends “pre-selling” an idea — for instance, offering a limited number of spots or seats into, say, a course you create and giving the test group specialized attention so you can see how to improve the content. Once it’s revised (or, if it’s software, once all the bugs are removed), you could open it up to your whole audience.

I see you include rental income, e-book sales and P2P loans as part of your passive income. Do you not consider your other internet income as passive? Is that why it’s not in the chart? Or did you not include it because you would rather not reveal it at this point? (I apologize if this question was already answered – I didn’t read through all the comments, and it’s been about a week since I actually read this post via Feedly on my phone)
Generating multiple streams of income can have a major impact on your finances. Even an extra income of $500 each month could go a long way towards paying down debt or increasing your investments. We often hear about the importance of diversifying our investments, but diversifying our income streams is just as important, particularly in difficult economic times.
That is a nice list of passive income sources. Actually, the most up-to-date list of dividend growth stocks is the list of dividend champions, maintained by Dave Fish. The list of dividend aristocrats is incomplete at best. For example, the dividend champions list has over 100 companies that have managed to increase dividends each year for at least 25 years in a row. The list of dividend aristocrats has no more than 50 – 60.
Seven of the ten counties in California with the lowest per capita incomes are located in the Central Valley. Two of the remaining three are rural counties in Northern California. This leaves Imperial County, which shares California's portion of the U.S.-Mexico border with San Diego County. All of these counties had populations not exceeding 1,000,000, and all of them are landlocked, with the exception of Del Norte County.
Stocks (shares) paying dividends are typically a reliable source of income but they have higher risk of capital losses than cash and bonds. So, it’s wise not to chase yield indiscriminately.  The 10 highest yielding stocks on the ASX 200 (the 200 largest companies in Australia) are shown in the table below.  But their share price performance on average over the last year has been underwhelming, as shown in the far right column:
“Start-up time” required: Poor – Experienced niche site builders will be well versed with outsourcing certain tasks and running through the whole process very efficiently, but when you first start out, it can take a long time to earn your first dollar from a niche site.  Doing research, designing the site, writing content, and doing proper SEO work can all be very time consuming, and the payoff isn’t always something you can rely on.

You are also free to choose a fund that is based on any index that you want. For example, there are index funds set up for just about every market sector there is — energy, precious metals, banking, emerging markets — you name it. All you have to do is decide that you want to participate, then contribute money and sit back and relax. Your stock portfolio will then be on automatic pilot.
What I’m doing: I view passive income as funny money to keep myself sane during this long journey. I estimate 2-10 years to get to my goal depending on how active I am. The dollars created are just points one can accumulate. I’ve made passive income goals for each passive income type and check in at least once a year like I am now to make sure I’m on track. Passive income is also carefully managed to minimize tax liability. When you can build a buffer for a buffer, you are then free to take more risks.
Here's an option that's still unfamiliar to many people but that has been growing in popularity: Lending money on a peer-to-peer basis. A major website for this is lendingclub.com, where investors have earned returns in the neighborhood of 4% or more annually. You'll be lending money to fellow individuals who have had trouble borrowing money through other avenues, and you can spread your dollars across many such folks to reduce the risk.
The website Fiverr.com lets people sell (and buy) all kinds of wacky services for just $5 a pop. Current services for sale include designing a visually-appealing signature, creating a customized sound effect, making a tough decision, and writing a personalized rap song. Just as with crafty projects, you don’t want to over commit to something that won’t earn you a big return, but if you have a skill that easily translates into a quick service, then this could be a good strategy for you.
We’ve discussed how to get started building passive income for financial freedom in a previous post. Now I’d like to rank the various passive income streams based on risk, return, and feasibility. The rankings are somewhat subjective, but they are born from my own real life experiences attempting to generate multiple types of passive income sources over the past 16 years.

My returns are based on full cash purchase of the properties, as it is hard to compare the attractiveness of properties at different price ranges when only calculating down payment or properties that need very little rehab/updates. I did think about the scores assigned to each factor, but I believe tax deductions are a SIGNIFICANT factor when comparing passive income steams.

Andrew Rafal, Founder and President of Bayntree Wealth Advisors in Arizona, recently told me about his push to get clients to diversify their income streams. The Great Recession feels like an eternity ago now that the economy is looking up, he says. The job market is strong and consumer confidence is through the roof. As a result, it’s possible people are getting a little too comfortable.
