To give you a preview of this post, what you will learn is that there are two key parameters that drive how viral growth happens, the Viral Coefficient, and the Viral Cycle Time. To fully illustrate the arguments, I have included two spreadsheet models (embedded) that you can play with interactively to see how viral growth works. There is a risk with this level of depth, that some readers will find this too technical, and if you find yourself reacting that way, may I recommend that you jump straight to the conclusion, which is under the heading Lessons Learned towards the bottom of the article.
What I did: I first identified my favorite places in the world to live: San Francisco, Honolulu, Paris, Amsterdam, New York City, and Lake Tahoe. I then looked up the median rent and housing prices for each city. Then I factored in private education costs for two kids to be conservative given I may not have two kids and public schools are often good enough. After calculating all vital costs, I then did a self-assessment of how happy I was making $50,000, $100,000, $150,000, $200,000, $250,000, $350,000, $500,000, and $750,000. I decided working 20 hours a week making $200,000 a year is the best income balance for maximum happiness. 
It’s easy to think as passive income as money earned while sitting on a beach sipping mojitos, but there is lots of work involved, says financial coach and retired hedge fund manager Todd Tresidder. If you’re worried about being able to save enough of your earnings to meet your retirement goals, building wealth through passive income is a strategy that might appeal to you.
While you’re setting up your new income stream, keep in mind that there truly is no such thing as free money. You’ll feel even more satisfied with the reward knowing what it took to get there. While there’s no one magic trick to getting passive income to work for you, with so many different methods, there’s surely one option that will fit your situation and skill set. Set up your passive income stream today to start making money, free up time and set yourself up on the path to financial independence.
But first, let’s about talk passive income! What is passive income? There are many different definitions out there, but mine goes something like this: Passive income is all about building online businesses that can work for you, that allow you to generate income, and grow and scale, without a real-time presence. In other words, you don’t trade time for money. You build something up front that can continue to work for you over time.
In 2014, A.L.S. Ice Bucket Challenge was among the best viral marketing challenges examples in the social network. Millions of people on the social media started filming themselves, pouring a bucket of ice water over their heads and sharing the video with their friends. The challenge was created to give support for fighting amyotrophic lateral sclerosis (ALS), also called Lou Gehrig's disease. People finished the challenge and then nominated the next person they knew on the social media to take the same challenge. By following this trend, Ice Bucket Challenge became a 'fab' on social media with many online celebrities such as Tyler Oakley, Zoe Sugg and huge celebrities and entrepreneurs like Justin Bieber, Mark Zuckerberg and Bill Gates participating.[76] Until September 2014, over 2.4 million ice bucket-related videos had been posted on Facebook, and 28 million people had uploaded, commented on or liked ice bucket-related posts. And about 3.7 million videos had been uploaded on Instagram with the hashtags #ALSicebucketchallenge and #icebucketchallenge.[77] The ALS association didn't invent the ice bucket challenge, but they sure received a huge amount of donation from this activity. It raised a reported $220 million worldwide for A.L.S. organisations, and this amount is thirteen times as much donation as what it had in the whole preceding year in just eight weeks.[78]
Brian had found a huge need for web design in the restaurant and food truck space. After getting tired of working with client after client, he decided to turn his service-based business into a product-based one. He made his services more standardized and productized. He eliminated all his client work and created templates and products to serve that market instead. And it’s been going great for him.
5) Determine What Income Level Will Make You Happy. Think back to when you made little to no income as a student. Now think back to the days when you just got started in your career. Were you happy then? Now go over every single year you got a raise or made more money doing something else. How did your happiness change at all, if any? Everybody has a different level of income that will bring maximum happiness due to different desires, needs, and living arrangements. It’s up to you to find out your optimum income level.
Thus, it's easy to dream of money just arriving, without our having to clock in to earn it. Fortunately, passive income streams don't have to be a dream. There are many sources, with examples including REIT dividend income, residual money, real-estate investments, interest, and other income-generating assets. Here's a look at 15 of them -- see which opportunities could work for you.
Definition: Unique Selling Proposition or USP is the one feature or the perceived benefit of a good which makes it unique from the rest of the competing brands in the market. It is that very reason which motivates a buyer to purchase that product even though it might be costlier than other products. Description: Unique Selling Proposition or USP is a very important concept used during the time when a company promotes its product through its advertisements in both TV as well as print media which eventually attracts a consumer to buy a particular product. The key to boost the sales of the product effectively through advertising is to highlight the USP of the product prominently. Unless you highlight the USP, consumers will not be tempted to buy your product. Every product should have its own USP, which makes it stand apart from other products in the similar category. USP is different for different products. Let’s take an example of a restaurant which is very famous across the world for its quick Subway Sandwiches. The company makes the sandwiches healthier for consumers. Consumers who are looking for a quick meal can walk into any subway outlet and get a quick sandwich made, which contains nutritional value. In this way the company is able to create its own niche market across town in India. The USP of the product is a nutritious sandwich at an affordable price. USP is a very important component in developing the product. A strong unique selling proposition makes you stand apart and also plays an important role in branding your product. But, USP alone can guarantee to a product’s success. Superior product quality and at par service, both before and after-sale are very important in creating the foundations of a market for a product. Always remember, with a distinct USP, the company doesn’t even have to bother about competition because if you have developed something which has not been developed by others, then you are the only player or a market leader in that specific product category (Example – iPpod by Apple).
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!
Ibotta: this is a bit different! You need to take a picture of your grocery receipts with your phone and upload them to the app. You will then receive between $0.25 to a few dollars per receipt as cash back for buying certain products. It’s so easy I can’t believe they actually give you cash for that. Plus you’ll get a free $10 bonus when you sign up!
Writing a book is an incredibly challenging task, and one that can take years to complete. Once the book is written and published, it doesn’t take any effort to maintain – unless you revised it down the road due to a change in your field. The risk is that no one downloads or buys your book, but there is considerable upside if you manage to find a following. There are a number of places to publish books online these days like Amazon.
All viral marketing examples — deliberate or accidental — have three things in common: the message, the messenger and the environment. Each part must be leveraged to create a successful viral marketing campaign. Viral marketing campaigns may be created by any size of business and can stand alone or be a part of a larger traditional campaign. The campaigns themselves may utilize a number of tools, such as videos, games, images, email and text messaging, free products, appealing to the emotions of users or viewers, raising awareness to a worthy cause, and making such products, ideas or media easy to consume and share. Viral marketing often relies on the help of an influencer, who has a large network of followers.

Another option: Consider starting your own real estate investment group. This is a great way to team together with other small investors, either via pooling your money together or simply by learning from eachother. According to Joseph Hogue, CFA from PeerFinance101.com, “The common bond in all real estate investing groups is that you help each other compete against the big money players to get the best returns.”

What happens if you have attrition in your customer base over time. An easy way to extend the model to take this into consideration would be to add a variable to model Attrition Rate as a percentage of the entire installed base at each cycle, and simply subract this from the total population at each cycle. This topic is nicely covered in this blog post by Andrew Chen: Is your website a leaky bucket? 4 scenarios for user retention.
Viral advertising is personal and, while coming from an identified sponsor, it does not mean businesses pay for its distribution.[6] Most of the well-known viral ads circulating online are ads paid by a sponsor company, launched either on their own platform (company webpage or social media profile) or on social media websites such as YouTube.[7] Consumers receive the page link from a social media network or copy the entire ad from a website and pass it along through e-mail or posting it on a blog, webpage or social media profile. Viral marketing may take the form of video clips, interactive Flash games, advergames, ebooks, brandable software, images, text messages, email messages, or web pages. The most commonly utilized transmission vehicles for viral messages include: pass-along based, incentive based, trendy based, and undercover based. However, the creative nature of viral marketing enables an "endless amount of potential forms and vehicles the messages can utilize for transmission", including mobile devices.[8]
