To model Viral Cycle Time’s effect on growth, I searched the web, high and low, looking for a pre-defined formula. To my great surprise, there was no formula that I could find that correctly calculated customer growth, and showed the impact of Viral Cycle Time. What was also surprising, was that I did find several blogs showing formulae for viral growth, but in every case, they appeared to make the same mistake, which was assuming that the entire customer base would continue sending out invitations for every cycle. So I collaborated with my partner, Stan Reiss, who turns out to be a whole lot smarter than I am, and he helped me develop the fomulae that are used in the more sophisticated model for viral growth below:

If you are too busy in your life and job and have lots of responsibilities, you need to play safe. One of the easiest and probably best options to start with for earning passive income to invest your money into high interest paying saving accounts. A simple search on comparison sites can give you a little insight into what kind of rates are being offered by the banks and financial institutions on the saving accounts. So start putting your extra money in high yield saving accounts.
Among the many passive-income opportunities that exist, interest is a very popular one, along with dividends. Unfortunately, we've been living in an environment of ultra-low interest rates for many years now, so even a savings account with $100,000 in it might only grow by $1,000 or $2,000 per year. Interest rates seem to be rising, though, so take heart -- and know that in many past years, bank accounts and CDs and bonds have paid rates of 5%, 8%, and even 10% or more.
Exploits common motivations and behaviors. Clever viral marketing plans take advantage of common human motivations. What proliferated “Netscape Now” buttons in the early days of the web? The desire to be cool. Greed drives people. So does the hunger to be popular, loved, and understood. The resulting urge to communicate produces millions of websites and billions of email messages. Design a marketing strategy that builds on common motivations and behaviors for its transmission, and you have a winner.
Messenger: Three specific types of messengers are required to ensure the transformation of an ordinary message into a viral one: market mavens, social hubs, and salespeople. Market mavens are individuals who are continuously 'on the pulse' of things (information specialists); they are usually among the first to get exposed to the message and who transmit it to their immediate social network. Social hubs are people with an exceptionally large number of social connections; they often know hundreds of different people and have the ability to serve as connectors or bridges between different subcultures. Salespeople might be needed who receive the message from the market maven, amplify it by making it more relevant and persuasive, and then transmit it to the social hub for further distribution. Market mavens may not be particularly convincing in transmitting the information.
​Udemy is an online platform that lets its user take video courses on a wide array of subjects. Instead of being a consumer on Udemy you can instead be a producer, create your own video course, and allow users to purchase it. This is a fantastic option if you are highly knowledgeable in a specific subject matter. This can also be a great way to turn traditional tutoring into a passive income stream!
To your point about Municipal Bonds, my concern is tax reform. While everything is mostly being worked behind closed doors (and likely wont ever see the light of day). There is still the chance they propose to limit the amount of the tax free nature of these bonds. While I dont sen panic in the streets, I do see a scenario where bond prices get additional pressure because municipalities have to increase rates due to people putting their money to work elsewhere.
The much loved model for bloggers and content creators everywhere and for a good reason…it’s pretty easy to write a 60-80 page ebook, not hard to sell say $500 worth a month through online networking, guest posting and your own SEO optimized blog, and well you get to keep a large whack of the pie after paying affiliates.  Hells yeah!  Continue reading >

This is a venture that is growing rapidly. You can create videos in just about any area that you like — music, tutorials, opinions, comedy, movie reviews — anything you want . . . then put them on YouTube. You can then attach Google AdSense to the videos, which will overlay your videos with automatic ads. When viewers click on those ads, you will earn money from AdSense.
In 1999, Daniel Myrick and Eduardo Sanchez began drumming up buzz for their now-legendary movie, The Blair Witch Project, using innovative techniques made possible by the relatively new culture of the Internet. The film is an early example of the “found footage” style that is made to look like amateur video shot by real people. Myrick and Sanchez, along with Artisan Entertainment, capitalized on the realistic look of Blair Witch to build a campaign around it that suggested the footage actually was real.
Now that we have the model built, we can play with the variables to see what effect they have. In the spreadsheet above, go to cell B11, and change the Conversion rate for invites (conv%) to 5%. This will make the Viral Coefficient less than 1. Now look at what that did to your population growth. Instead of continuing to grow, it grows to 20 people, and then stops.

Part of providing value is building trust. Don’t link to things that aren’t of good quality or people won’t trust your recommendations. The other part of making an audience is consistency. It matters less how often you post than how consistently. If you only have time to do one post a month, that post should come out on the same date and time each month.

One of the easiest ways to increase your passive income is to shift your savings to a bank that pays a higher yield on your savings — for example, Discover Bank and EverBank pay almost 1% for your money. Although it doesn’t sound like much (especially in this low interest environment), little things do add up and eventually interest rates will rise.
Another way to generate passive income is to invest and be a silent partner in a business. This is very risky, but with risk comes the potential for high returns. For example, several years ago both Lyft and Uber were looking for private investors to invest in their companies. Today, they are worth billions - but you as an investor would only reap that benefit if they go public via an IPO, or get acquired. So, it's risky.
We pitched to an angel investor group. They were very excited about the idea but wanted to know who amongst us (doctor, accountant, salesman) was doing the coding. When they heard we were outsourcing it, the wind went out of their sails immediately. They did want to meet with us again once we brought a coder on board but that person proved elusive to find. Coders in our area are looking for the steady paycheck, not willing to gamble on a startup.

Online courses have exploded in the past five years. Experts and creators can now create video courses to teach others their craft. A course can be about anything that people want to learn. Friends of mine have created courses and say the amount of effort is similar to writing a book. But once its done and starts to sell, it’s a solid passive income stream.
There is debate on the origination and the popularization of the specific term viral marketing, though some of the earliest uses of the current term are attributed to the Harvard Business School graduate Tim Draper and faculty member Jeffrey Rayport. The term was later popularized by Rayport in the 1996 Fast Company article "The Virus of Marketing",[12] and Tim Draper and Steve Jurvetson of the venture capital firm Draper Fisher Jurvetson in 1997 to describe Hotmail's practice of appending advertising to outgoing mail from their users.[13] An earlier attestation of the term is found in PC User magazine in 1989, but with a somewhat differing meaning.[14][15]
