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.

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]
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.
Thanks for the great article…although I have to point out many of the items listed are not passive but active, such as selling bodily fluids, writing blogs or resumes, and collecting bottles and cans. To be truly passive, the income source must require no effort on your part (after initial setup). Real estate, dividends, P2P lending…these are truly passive income sources.
Diversify safely but DIVERSITY. You do not need to get the best and highest return all the time. If so, you are not earning passive income you are earning active income which is taxed differently (see IRS.GOV passive -vs- active income definitions). As an investor you do not need to be chasing ‘the almighty dollar’. This is a losing proposition. Make the dollar come to you.
The list of passive income ideas could go on forever. As you search for the best fit, keep an eye out for ideas that show positive long-term track records. Do other people make money on the idea? Has it come back to bite someone who tried it? Some people ask me about passive income options like drink, vending, or other rental machines in public places. The bottom line? Don’t fall for any passive income ideas that promise a quick return or require huge amounts of money upfront. They will sabotage your other financial goals. Look for ideas that are steady, profitable, and trustworthy. Do your research. And never go into debt!
Blogging is still going to take work starting out. That path to $5,000 a month didn’t happen overnight but just like real estate development, it build up an asset that now creates constant cash flow whether I work or not. I get over 30,000 visitors a month from Google search rankings, rankings that will continue to send traffic even if I take a little time off.
However, when you lack the money, you need time. You'll need to invest the upfront time now in order to reap the benefits of automatic income later. It just doesn't happen overnight. So don't expect it to. However, you can do this without quitting your day job. All it takes is some sincere effort over a consistent period, and voila! But, to get there, you'll need to consistently burn the midnight oil or get up at the crack of dawn. Your choice.

ie first you need to haul ass and do something crazy, eg write a quality 20,000 word ebook (insanely not passive hahahah), but then you get to sit back and enjoy seeing PayPal sale messages pop up on your iPhone each morning as sale after sale after sale is made…on an ongoing basis and without any additional work. That’s some seriously Pina Colada flavored passive goodness!
However, this comes back to the old discussion of pain versus pleasure. We will always do more to avoid pain than we will to gain pleasure. When our backs are against the wall, we act. When they're not, we relax. The truth is that the pain-versus-pleasure paradigm only operates in the short term. We'll only avoid pain in the here and now. Often not in the long term.
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. 
Do you think it’s possible to build a blog from scratch, outsourcing the work from day one (assuming I have some cash that can cover the initial expenses until the blog generates enough income to at least break even)? In other words, do you think you could you have spent your $500 max per month for the writer, social media expert, etc to build your blog to the point it’s earning the same amount of money it does now?
But as with everything, there are cons to go with the pros. While a good viral marketing campaign can bring massive awareness about your brand in a cost-effective manner, it also has the capability to dilute your brand. Or at its very worst, build negative buzz regarding your brand and products. This is when “too much of a good thing” may just hurt your work in building your organization’s credibility.
Where blogging requires frequent, less-lengthy content, a book can be something you work on for months at a time and publish it for sale. And it can become more than just passive income. In fact, UK author Mark Dawson makes close to half a million dollars a year from self-publishing his books. On a smaller scale, Joseph Hogue makes about $2,000 per month writing and self-publishing financial books. If these guys can do it, anyone can.
3. Start as soon as possible. Building a livable passive-income stream takes a tremendously long time, largely because of declining interest rates since the late 1980s. Gone are the days of making a 5%-plus return on a short-term CD or savings account. Today, the best 12-month CD is at 2.5%, and the best money-market rate is about 1.85%, which is not bad, considering such rates were below 0.5% just a couple of years ago. Know that every $100 you save can generate at least $2.5 in passive income.

If you have decent writing skills you can start a retainer writer business. Mastering your pitch will put you in a position where you can land awesome writing gigs. You can then complete the work yourself as you establish yourself in this space, and from there, the sky is the limit. Outsourcing is key to creating a passive income stream from this idea.
The appeal of these passive income sources is that you can diversify across many small investments, rather than in a handful of large ones. When you invest directly in real estate, you have to commit a lot of capital to individual projects. When you invest in these crowdfunded investments, you can spread your money across many uncorrelated real estate ventures so individual investments don't cause significant issues.
The craziest part of this was I’d wake up in the morning and there would be more money in my bank account, from people who had bought my book overnight. When you think about it, an online store that sells something that’s digital is something that’s open 24 hours a day, 7 days a week, 365 days a year. Using tools, software and systems, you can automate the delivery process so you literally don’t have to do anything to serve that audience. That’s super powerful.
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]
