Turn your burning passions and daily musings into an entertaining audio show. Whether you want to talk about history, food, finance, or music, you can record and edit episodes from the comfort of your home. Once you have a large group of listeners, you can earn money from podcast sponsorships, affiliate marketing, selling products or eBooks, or crowdfunding. While you’ll have to produce episodes consistently, the time involvement is minimal and you can record several shows in advance.

Haha, that is too funny. I wanted to make an app back in the day called “MyShares” (You can probably tell how I cam up with the name at the time). The idea was that I would loan out books and DVD’s and then would never get them back. Then I thought, how cool would it be if I could rent those items out and that would motivate people to bring them back. Obviously, books and DVD’s are cheap, so this isn’t the money maker. The idea that would probably make the most money would be things like tools, ATVs, etc.
In 2012, even I wrote a 150-page eBook about severance package negotiations that still regularly sells about ~35 copies a month at $85 each (2nd edition for 2017) without any effort. In order to generate $2,975 a month or $35,700 a year in passive income as I do now, I would need to invest $892,500 in something that generates a 4% yield! To earn $10,000 a year in passive income would therefore need roughly $250,000 in capital.

There are many people who get paid vast amounts of money to become the CEO of a company, play professional sports, or star in a movie. Earning a high active income is often a lot of hard work and requires a dedication beyond most of us. It’s also limited because no matter how much money you get paid you still need to show up to work to earn your money.
Or you could do joint ventures/strategic alliances for your business or for other businesses and make residual cash flow for $0 investment.. that’s what I do lol. No money, no risk, little time, 20+ years working from home. Just connect companies and take a %, use the Internet to do it locally or globally, be the intermediary & connect companies…. ;-)
You’ve probably heard of affiliate marketing before – it’s when you earn a commission by promoting a product. The product you promote online should be something you’re knowledgeable about and that you believe is high quality. Common sense, right? You’d be surprised by how many affiliate marketers forget that principle, but that’s a whole other story.
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.

In equity valuation, residual income represents an economic earnings stream and valuation method for estimating the intrinsic value of a company's common stock. The residual income valuation model values a company as the sum of book value and the present value of expected future residual income. Residual income attempts to measure economic profit, which is the profit remaining after the deduction of opportunity costs for all sources of capital.
