As for me, I started focusing on passive income last year, but have owned rentals for 5 years. $25k now outside retirement accounts in mostly real estate. Looking to invest another $500k cash into real estate to get about $65k, and then 1031 under performers next year to hopefully boost that a bit higher. Heavy in real estate, but feels lower risk than the stock market to me if you have cashflowing properties. Real estate is inflation adjusted, and built in cashflow raise when the loan pays off.
Wow! What an awesome list! My favorite is the stock photography because I love photography. I have had some success there, particularly with one photo I make some decent income from. I think the key with stock photography is finding a shot that is high demand. Then, find a new unique way to frame that shot. This is the reason my St. Louis Arch photo is a top 10 on both ShutterStock and iStockPhoto. Thanks for the awesome ideas above!

Beta Testing: Identify top influencers who can try your new product in beta and motivate them to review and talk about it before it goes to market. Their followers will be privy to ‘classified’ information that makes them feel great and they will want to know more about the product. Make sure that any bugs or confusion that are identified in this phase are solved before the product goes live. It could turn into a lessons learned blog!
Unlike having to either create something or store a physical inventory of something, selling digital products requires no overhead and no active work to earn money. The blog Paper & Oats put together a great guide on how to get started selling on Etsy. In this guide, they share a few ideas on digital products you can put together and sell in your Etsy store. If you’re someone who’s creative and knows how to design great-looking digital files, this might be a perfect option for you.
Rental properties are defined as passive income with a couple of exceptions. If you’re a real estate professional, any rental income you’re making counts as active income. If you’re "self-renting," meaning that you own a space and are renting it out to a corporation or partnership where you conduct business, that does not constitute passive income unless that lease had been signed before 1988, in which case you’ve been grandfathered into having that income being defined as passive. According to the IRS, "it does not matter whether or not the use is under a lease, a service contract, or some other arrangement."
The five forces model of analysis was developed by Michael Porter to analyze the competitive environment in which a product or company works. Description: There are five forces that act on any product/ brand/ company: 1. The threat of entry: competitors can enter from any industry, channel, function, form or marketing activity. How best can the company take care of the threat of new entrants? 2

What I Do: I’ve set up multiple investment accounts outside my main operations bank that deals with working capital e.g checking, paying bills. By transferring my money to a couple brokerage accounts and two other banks as soon as it hits my main bank I no longer have temptation to spend on frivolous things. As a result, I can wake up 10 years later and reap the rewards of compounding. My 401(k) is the best example where constant contributions over 18 years has grown to over $500,000 without any savings pain given it just became a part of life. Real estate is also a fantastic asset class for the long term. It’s fantastic to enjoy your home, pay down your mortgage each month, and end up with a paid off asset that has likely appreciated during your time of ownership. 

There are three main categories of income: active income, passive income and portfolio income. Passive income has been a relatively loosely used term in recent years. Colloquially, it’s been used to define money being earned regularly with little or no effort on the part of the person receiving it. Popular types of passive income include real estate, peer-to-peer (P2P) lending and dividend stocks. Proponents of earning passive income tend to be boosters of a work-from-home and be-your-own-boss professional lifestyle. The type of earnings people usually associate with this are gains on stocks, interest, retirement pay, lottery winnings, online work and capital gains. 
But nowadays, there is so much opportunity if you search for brand-suitable domains and also keyword-rich or otherwise popular names on the myriad of new domain name extensions like .io, .at etc.  And I should know, because I’ve paid several domain squatters a king’s ransom to purchase these sorts of domain names in the last few years!  Continue reading >
It’s not just the little guys like me who are being squeezed by the constant updates. Even YouTube’s top creators have expressed frustration with changes to the YouTube monetization platform. It’s constantly changing and evolving, so you must be willing to adapt. Plus, it helps having a blog so you’re not relying on a single platform or your income.
Who doesn’t like some down and dirty affiliate fees?!  Especially if you realize it can be even easier to make money this way than with an ebook.  After all, you simply need to concentrate on pumping out some content for your own site and getting the traffic in, often via Google or social media.  Unsurprisingly, most people can enjoy their first affiliate sale within 30 days of starting a blog.  Continue reading >
People have a lot of stuff—and they’re always looking for inexpensive ways to store it. What could be easier than having people pay you to store their stuff? Building passive income by offering storage could involve a large-scale investment of buying a storage facility (with cash!) or something simpler like offering your basement or shed. You’ll just need to ensure their items are safe and secure.
Real Estate: I currently own one rental property in San Francisco which I bought in 2003 (2/2 condo), one vacation rental in Squaw Valley, Lake Tahoe (2/2 condo), and my primary residence. Real estate is my favorite asset class to build wealth because it is easy to understand, tangible, provides utility, and rides the way of inflation. I recommend individuals try and get neutral inflation by buying their primary residence as young as possible. The power of inflation is just too hard to counteract.
A quick look at the table that shows the effect of varying the Viral Cycle Time shows that customer growth is dramatically affected by a shorter cycle time. For example, after 20 days with a cycle time of two days, you will have 20,470 users, but if you halved that cycle time to one day, you would have over 20 million users! It is logical that it would be better to have more cycles occur, but it is less obvious just how much better. A quick look at the formula tells the whole story. The Viral Coefficient K is raised to the power of t/ct, so reducing ct has a far more powerful effect than increasing K.
For starters, many websites are using them–so there’s a big market for stock photography. It’s no shocker either, as one study found, that 65% of people are visual learners. In fact, when people hear information, they remember about 10% of that information three days later, but if a relevant image is paired with that same information, Brain Rules found that people retained 65% of the information three days later–a 55% increase.
To make the Viral Cycle Time as short as possible, we can apply the same thought process that we use in Building a Sales and Marketing Machine, where we look at what are the customers motivations and negative reactions as they flow through the viral cycle.  For example, when I reach the stage where I have to enter my friends addresses, I will not bother to do very many if I have to look them up in another program, and copy and paste them one-by-one into the browser. You can solve this problem by providing me with Facebook Connect integration to invite my Facebook friends, and an adapter to import my email contacts. (Check out the “Share This” button on the left side of this post as an example of how this can be done.) Getting at email contacts is easy with web mail clients like GMail, etc. – but harder with Outlook. However viral products like LinkedIn have created Outlook adapters that you can download. It is also feasible to get at that information via Outlook Web Access (OWA) provided you can deal with the security concerns.You should also be looking for ways to encourage customers to invite people at various junctures in their use of the application. And of course, you should be asking yourself the question: is the value proposition of your product really that compelling that your customers will want to share it with others? Another great way to increase virality is to incent customers with a reward for every customer they successfully convert. Since this can result in an individual feeling guilty that they are making money off their friends, the best way to do this is to also provide the friend that is receiving the invitation with an equal incentive. Now your customer will feel like they are doing their friends a favor.
Provides for effortless transfer to others. Public health nurses offer sage advice at flu season: Stay away from people who cough, wash your hands often, and don’t touch your eyes, nose, or mouth. Viruses only spread when they’re easy to transmit. The medium that carries your marketing message must be easy to transfer and replicate: email, website, graphic, software download.
Marketers and agencies commonly consider celebrities as a good influencer with endorsement work. This conception is similar to celebrity marketing. Based on a survey, 69% of company marketing department and 74% of agencies are currently working with celebrities in the UK. The celebrity types come along with their working environment. Traditional celebrities are considered as singles, dancers, actors or models. These types of public characters are continuing to be the most commonly used by company marketers. The survey found that 4 in 10 company having worked with these traditional celebrities in the prior year. However, people these years are spending more time on social media rather than traditional media such as TV. The researchers also claim that customers are not firmly believed celebrities are effectively influential.[43][44]
The introduction of social media has caused a change how viral marketing is used and the speed at which information is spread and users interact.[35] This has prompted many companies to use social media as a way to market themselves and their products, with Elsamari Botha and Mignon Reyneke stating that viral messages are "playing an increasingly important role in influencing and shifting public opinion on corporate reputations, brands, and products as well as political parties and public personalities to name but a few."[35]
