Amazing that you saved between 50% to 75% living in NYC…I think that is one thing holding me back…the cost of living here. I’d like to invest in real estate, but I can barely afford to buy a place to live. I don’t need a large income to be happy, but I probably do need an income to support living in NYC as we don’t plan on leaving. The only thing I’m doing at the moment is saving in my 401K, IRA and a I dabble in stocks and P2P lending.

The disadvantages to consider with viral marketing include the nuisance factor. Due to the large amount of email people receive daily, viral marketing messages may be viewed as spam. Another consideration is negative marketing buzz. A message may not be construed as intended, and could be discussed in a negative manner. Viral marketing can also be hard to measure. 
The first time I did affiliate marketing was way back in the day on my architecture exam website. I connected with a company that sold practice exams, which gave me $22 for every person who bought one of their exams via my site. Since then, I’ve generated over $250,000 simply by recommending that product alone. Again, this is a product that was not mine, but one that has still been helpful to my audience. This was all done with thousands of visitors a month. Not millions, or even hundreds of thousands.
Between 1996–1997, Hotmail was one of the first internet businesses to become extremely successful utilizing viral marketing techniques by inserting the tagline "Get your free e-mail at Hotmail" at the bottom of every e-mail sent out by its users. Hotmail was able to sign up 12 million users in 18 months.[67] At the time, this was historically the fastest growth of any user based media company.[68] By the time Hotmail reached 66 million users, the company was establishing 270,000 new accounts each day.[68]
The CD is one of the most effective ways to create passive wealth over time and has been used by investors for generations. Ask your grandparents; it is highly likely they own CDs (TDs) with their local bank or Credit Union. This is done by creating CD ladders to maximize effectiveness. Most Bank and Credit Union CDs have zero fees attached unless you cash out before maturity.
7) Never Withdraw From Your Financial Nut. The biggest downfall I see from people looking to build passive income is that they withdraw from their financial nut too soon. There’s somehow always an emergency which eats away at the positive effects of compounding returns. Make sure your money is invested and not just sitting in your savings account. The harder to access your money, the better. Make it your mission to always contribute X amount every month and consistently increase the savings amount by a percentage or several until it hurts. Pause for a month or two and then keep going. You’ll be amazed how much you can save. You just won’t know because you’ve likely never tested savings limits to the max.

What I’m doing: I use this site to write out goals like 1) Generating $200,000 a year working 4 hours a day or less, 2) Trying to make winning investments, and 3) Keeping track of my passive income streams with free financial tools. My site and the community helps keep me accountable for progress. It’s important I do what I say, otherwise, what the hell is the point? You should consider starting a site or at least a private journal. Write out your specific goals, tell several close friends and stick to the plan.
Apple maintains it’s viral appeal, with the iPhone X through their launch of the "Selfies on iPhone X" campaign. The secret to this example of viral marketing (which has clocked up over millions views both online and offline) is very simple: a product so great that it turns people into fans of the brand all on its own. People love themselves. If they have the possibility of spreading this love digitally through selfies, it’s almost a guaranteed win. The iPhone X’s brilliant selfie feature spread virally through various media forms before apple repurposed the viral content into one masterpiece, the iPhone X selfies film. As one of the YouTube comments says, “It’s the most beautiful thing I’ve ever seen”… This viral marketing through video has allowed Apple to spread key features such as their Portrait Lighting effects and their TrueDepth camera.
