I like the way you have listed the ways to earn extra income and was quite surprise that you did not make mention of network marketing, which is a way to make extra income without quitting your regular, though most people view mlm as a pyramid scheme but the real pyramid scheme is a regular 9 to 5, because you can only have one president of a company at any given time and network marketing business model to promote product that can be used is really cheap to join and can offer a substantial extra income or what do you think?

For example, you might take photos and have them available for a fee at sites such as shutterstock.com or istockphoto.com. Similarly, you can create and upload designs at sites such as zazzle.com and cafepress.com, where people can buy them imprinted on shirts, mugs, and so on. Similarly, if you write an e-book (which can be as short as 6,000 or so words), you might find that people are interested in buying it, perhaps via Amazon.com's direct publishing service.
A REIT is a company that owns, operates or finances real estate and allows anyone to invest in portfolios of real estate assets, the same way as stocks: you can purchase individual stock or exchange-traded fund (ETF). You can then earn a share of the income produced through the real estate investment without having to own, manage or finance a property.

2. You clearly have plenty of money already. Just more padding in your already cushy nest. This is not the story for a lot of people. Your title should be “How to become richer than you already are without working.” But, actually the investment one is the only one that would make money without actual WORK. Running rental properties is a lot of work, and so is running a business, or even a blog. Sooooo…..while there might be some truth to this, I think it’s mostly grass that looks greener because it’s on the other side of the fence.

Remember, a successful business solves people’s problems. At first, you’re going to have to do the legwork and put in the time. But it’s about building something now so you can reap the benefits later, with the help of software, tools, automation, and people you hire. In this way, you can then turn this business that solves people’s problems into something that generates passive income for you!
Viral marketing, unlike word-of-mouth marketing, has a compounding effect. A consumer tells five to ten people, and then those five to ten people tell another five to ten people. The driving force behind most viral campaigns is the passion a consumer carries. It's like a virus that continuously infects more people and spreads without requiring any more marketing effort.
I enjoy how you lay out real numbers. A lot of people wouldn’t do that. While you admit that you are somewhat conservative, I think the $1M in CD’s is just too conservative. Assuming you don’t need the cash flow now (which you say you just save anyways) then all that could be invested for potentially higher returns. For example, what if you bought San Francisco real estate along the way instead of CD’s. Or, an SP500 Index fund. I bet your average return would have been higher than 3.75%. Sure you could lose it, but the point is if you don’t need the cash flow now, you should try to increase that nut as high as possible until the day you actually need it. Your nut could be $5M right now if you had invested in asset classes other than CD’s for the last 14 years. Don’t get me wrong, you have done far better than me, but I guess I would take a little more risk if you don’t rely on that cash flow.
Viral marketing strategies often forget about the pre-launch phase of a campaign. A easy way of ensuring that a viral marketing campaign goes viral is to start a conversation online where most of your audience is to build up hype around the campaign before it goes live. Build a plan where colleagues are involved to help get the conversation started. Maybe even include affiliates or related companies, who could gain from promoting the campaign, to help get the word out to as many people as possible. What will this achieve? This is get more people talking and peak their interest so your campaign will start strong and it will cost less to get the momentum going. From launching a teaser campaign to building anticipation through content on social media, pre-launch can sometimes be just as important as the actually promotion phase.

What’s also really important to realize here is that when I took the exam I was teaching people to study for, I didn’t get a perfect score. In fact, I didn’t even get close to a perfect score. I passed. But I also knew a lot about this exam—way more than somebody who was just getting started diving into studying for it. And it was because of that, because I was just a few steps ahead of them, that they trusted me to help them with that information. To support this, I provided a lot of great free value to help them along the way. I engaged in conversations and interacted in comments sections and on forums. Most of all, I just really cared about those people, because I struggled big-time with that exam myself.

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.
The Lake Tahoe property continues to be 100% managed by a property-management company. It feels amazing not to have to do anything. I can't wait to bring up my boy this coming winter to play in the snow! I could go up this winter, but I want him to be able to walk and run comfortably before he goes. I've been dreaming of this moment for over 10 years now. The income from the property is highly dependent on how much it snows. Summer income is always very strong.
I have six rental units which are a good source of passive income. I don’t use a property manager because you are right…they take about 10% of your rent. There are really only 2 things that tenants call about: 1. A plumbing issue 2. Heat/Air problems. Just find a plumber and heat/air guy you can trust. I travel a lot for my primary job. When a call comes in from a tenant, I can call the repair guy in just as easy as a property manager.
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.
You don’t have to invest individually to take advantage of dividend paying stocks (i.e. investing in an ETF like DVY, which currently has a 3.16% dividend yield – almost 4%). And while your math is indeed correct, there is more to dividend paying stocks that just the math. The reason the companies pay dividends is typically because of their underlying strength, steady growth, etc. These companies can be good investments for the long run. As such, it might not make sense to sell.
Before the challenge, ALS was known to much fewer people. But things changed after the challenge, and it was everywhere on Twitter, Facebook, YouTube, news, events, etc. The reason was the visibility created by the campaign. You need to create awareness about your brand through various marketing channels. People will prefer to buy from you only if they know about you.
They also launched an incredible Retirement Planning Calculator that pulls in real data from your linked accounts to run a Monte Carlo simulation model to output the most likely results of your financial future. I strongly suggest you run your own numbers, play around with the income and expense variables, and see how you stack up. It’s all free and easy to use.
The U.S. Internal Revenue Service categorizes income into three broad types, active income, passive income, and portfolio income.[1] It defines passive income as only coming from two sources: rental activity or "trade or business activities in which you do not materially participate."[2][3] Other financial and government institutions also recognize it as an income obtained as a result of capital growth or in relation to negative gearing. Passive income is usually taxable.
There are now two ways to sell on Etsy–physical and digital products. With physical products, you can either create something unique such as jewelry or buy and resell something–for example, vintage clothing. Etsy has been a great marketplace for a long time, helping creative people sell their goods. The problem is, selling physical products isn’t exactly passive income.

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.
