I have not. While I am intrigued with the possibility of making online income, it seems to be less passive then how I want to spend my time. Regarding your blog / site, you have done quite well for yourself. However, you have to keep pumping out content or your site would eventually go out of business. That sounds like more of a commitment then I would want. Regarding your book sales, it is probably relatively passive now, but certainly was not when you were writing the book. Now if you love it, great. Just not for me.
The surveys from home, you added a link for “everything we needed to know” it sent me to a site where I had to pay them $35 or $45 to get started. It doesn’t say anything about how, until you pay them. You sent us too the site BUT, have you checked it? Is it safe? Will they take my $, & I get nothing? If you say its OK, then fine, but usually these things are bad news. I fell into one when I was young. Proof reading at home. They sent you a book on how to do it, & then a “LIST” of all the company’s that hired at home proof readers. Well, they sent me the book, which was fine. But, the list they sent me had nothing but company’s that only hired people with long time prior experience proof reading. So, it was useless to me. ;(

Find the thought leaders in your particular industry, and find how what they’re saying about the industry. Many thought leaders put out white papers, free webinars and other useful information to attract an audience- and potential future clients. The information must be useful, in order to keep the reader engaged, and it can be a great reference for you.

The source of pension payments is determined by the portion of the distribution that constitutes the compensation element (employer contributions) and the portion that constitutes the earnings element (the investment income). The compensation element is sourced the same as compensation from the performance of personal services. The portion attributable to services performed in the United States is U.S. source income, and the portion attributable to services performed outside the United States is foreign source income.

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.
Who cares, especially when very conservatively, the ultimate passive income includes a six digit or more base lease, plus an estimated additional six digits or more for rate increases and another six digits for more for various smaller and one bigger technology increase at 25 years. All four (base, rate, smaller and mega technology increases) combined, certainly could yield much more depending upon inflation, rate increases and technology increases?
Attributable to compensation for services performed in Connecticut or income from a business, trade, profession, or occupation carried on in Connecticut (including income derived directly or indirectly by athletes, entertainers, or performing artists from closed-circuit and cable television transmissions of irregularly scheduled events if such transmissions are received or exhibited within Connecticut);
Unfortunately, I can’t answer that conclusively one way or the other. It all depends on you, what you like to do, your work ethic, personality, etc. If you are a good writer perhaps you could write a book and make money that way. Or, you could start your own website and do affiliate marketing. Just because you are young it doesn’t mean you can’t make money doing at least a few of these ideas. I wish you luck in your money making efforts!

I am 30 years old and am retired. Previously, I made a modest salary as an Army officer. I own three duplexes and a quadplex in central Texas (10 rental units in all), and each of the properties provide me with net rental yields in excess of 15%. The last deal is actually an infinite return as my partner paid the down payment in return for a 50/50 split on a property that would otherwise provide a net rental yield of 18%. The above net rental yields also factor in an excellent property management team who manages my properties while I pursue other investment opportunities. To date, I have never interacted with any of my tenants nor have I ever had to personally deal with any maintenance issues.
The growth in the IT sector is attributed to increased specialisation, and an availability of a large pool of low-cost, highly skilled, fluent English-speaking workers – matched by increased demand from foreign consumers interested in India's service exports, or looking to outsource their operations. The share of the Indian IT industry in the country's GDP increased from 4.8% in 2005–06 to 7% in 2008.[214] In 2009, seven Indian firms were listed among the top 15 technology outsourcing companies in the world.[215]
My dad is in  a similar situation as we speak, things have not been going well for him at work (but I do think he has himself to blame) and seems likely he will get let go.  Mr. Budgets and I both see how our parents are and we totally want to be on the other end of the spectrum when it comes to how they handle money. It motivates us to save and invest even more.
"You know what they say: 'Don't work for your money. Make your money work for you,'" Jenna Goudreau, Managing Editor of Make It, CNBC's new site focusing on all things money, tells Bustle. "That's exactly the goal with passive income: By being smart about the resources you already have, an initial investment of effort can eventually earn you money while you sleep."
Finally, make sure you can service multiple types of clients. This is the best egg to have. Even for something as simple as a dog walking business, you can service multiple types of clients. For example, you can offer a puppy walking service and an adult walking service. You can have weekends at the park services. You can offer to take the dog to the groomers. Try to meet client’s individual needs.
Others may define it more narrowly, but to me, PPC arbitrage basically involves setting up PPC ads (via Google AdWords or similar platform) and directing the traffic that results from ad clicks to a landing page or straight to an affiliate link (which many platforms don’t allow anymore).  The goal is obviously to earn more from the affiliate income than spent on the ad clicks.  You aren’t adding any value, but merely earning more from traffic than what it costs you to generate that traffic.
Portfolio income can come from multiple sources – interest/bond coupons, stock dividends, financial strategies including derivatives and capital growth.  Each offers some cash flow and some also offer potential capital gain with some risk from liquidity and volatile prices.  In this low-yield environment, many investors rely too heavily on cash flows and to pursue this are venturing further into riskier areas than they’d normally consider.
