1) Save Like Nobody Owes You Anything. Passive income starts with savings. Without a healthy amount of savings, nothing works. Your overall “Money Strength” will be an F- if you do not build a financial nut. In our current low interest rate environment, you must save even more than before. It’s important to also realize that the savings I am referring to is AFTER-tax savings. You need to save money after contributing to your 401k and IRAs since you can’t touch pre-tax retirement accounts without a penalty until 59.5. Ideally everyone should max out their pre-tax retirement funds first, but if you don’t have enough funds and want to retire earlier then a decision to have more accessible post tax money will still work.
On March 6, 2012, Dollar Shave Club launched their online video campaign. In the first 48 hours of their video debuting on YouTube they had over 12,000 people signing up for the service. The video cost just $4500 to make and as of November 2015 has had more than 21 million views. The video was considered as one of the best viral marketing campaigns of 2012 and won "Best Out-of-Nowhere Video Campaign" at the 2012 AdAge Viral Video Awards.
Viral content reaches people in different ways, depending on the platform they are using. YouTube users, for example, can browse trending videos. According to YouTube Help, YouTube evaluates signals such as the video’s view count, rate of growth in views, where the views originate from (i.e., YouTube search results vs. an embedded video in a blog post), and when the video was published.

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)

Thanks for the great article…although I have to point out many of the items listed are not passive but active, such as selling bodily fluids, writing blogs or resumes, and collecting bottles and cans. To be truly passive, the income source must require no effort on your part (after initial setup). Real estate, dividends, P2P lending…these are truly passive income sources.

Using influencers in viral marketing provides companies several benefits. It enables companies to spend little time and budget on their marketing communication and brand awareness promotion.[47] For example, Alberto Zanot, in the 2006 FIFA Football World Cup, shared Zinedine Zidane's headbutt against Italy and engaged more than 1.5 million viewers in less than the very first hour. Secondly, it enhances the credibility of messages.[48][49][50][51][52] These trust-based relationships grab the audience's attention, create customers' demand, increase sales and loyalty, or simply drive customers' attitude and behavior.[50][51] In the case of Coke, Millennials changed their mind about the product, from parents' drink to the beverage for teens.[53] It built up Millennials' social needs by 'sharing a Coke' with their friends. This created a deep connection with Gen Y, dramatically increased sales (+11% compared with last year) and market share (+1.6%).[53]

1. The batting cage idea is very risky. I’ve seen many of them close over the years and it is not anything close to passive income if you want to keep the business going. You have to continually promote it and target youth leagues, coaches, schools etc to catch all of the new players who grow up and want to play. I’ve played at probably 8 batting cages over the years and 7 of them closed.

Venture debt ($12,240 a year): The first venture-debt fund has returned almost all my initial capital, so I decided to invest $200,000 in the second fund. I took a risk investing $150,000 in my friend's first fund, so I'm hoping there's less risk in the second fund, given he has four more years of experience on top of his 12-plus years of experience running a venture-debt portfolio for another company.
Developing passive income is different. With the exception of one of my passive income streams (cryptocurrency mining), all of the others require real, hard work. Truly, I understand the barriers for people getting into building alternative income streams. I would say that most people WANT passive income, but truly aren’t willing to put in the blood, sweat, and tears to make it happen.
It's important also to realize that the success of a viral campaign depends on the vehicles used to transmit the message. There are companies that are more virally equipped than others. To create a strong viral link, the message must be able to transport from television advertising to radio and other extended means of broadcasting to the power of the Internet.
When you start your marketing campaign, it is crucial to create the best possible content to differentiate your brand. Promotion should be your next step. For promoting the brand effectively, Dove had strong social media strategies, which even lead to celebrities and other brands joining the conversation and sharing the video with others. Shareability is a huge factor for making your campaign a success. Involving customers in your campaign and providing them a platform for discussion is an invaluable way to develop customer relationship.
I’ve built several businesses since 2008 using one or more of these models. I’ve been featured in magazines and articles across the globe, and since I started my journey I’ve generated over $5M in earnings from these businesses. All of my income and expenses for those businesses dating back to October 2008 have been tracked publicly on SPI.com. You can see 10 years of income reports here.
When I started building my architecture-related business in 2008, I made my first dollar through advertising. I’d spent a lot of time and money building the site and getting traffic. Then one day I threw an ad on the site one day, and I made $1.18. Sure, I could find that much under my couch cushions—but that’s not the point! The point is that I was able to build something online, put an ad up, and make money without having to do anything. I learned it was possible, and it motivated me to move forward.
Among the first to write about viral marketing on the Internet was the media critic Doug Rushkoff.[16] The assumption is that if such an advertisement reaches a "susceptible" user, that user becomes "infected" (i.e., accepts the idea) and shares the idea with others "infecting them", in the viral analogy's terms. As long as each infected user shares the idea with more than one susceptible user on average (i.e., the basic reproductive rate is greater than one—the standard in epidemiology for qualifying something as an epidemic), the number of infected users grows according to an exponential curve. Of course, the marketing campaign may be successful even if the message spreads more slowly, if this user-to-user sharing is sustained by other forms of marketing communications, such as public relations or advertising.[citation needed]
