​Self Publishing is mainstream today. When you purchase an eBook off of Amazon there’s a pretty good chance you’re buying a self-published book. Self-publishing is also ridiculously easy. I tried this a few years ago and couldn’t believe how simple the process was. To self-publish a book you’ll first need to write and edit it, create a cover, and then upload to a program such as Amazon’s Kindle Direct Publishing. Don’t expect instant success though. There will need to be a lot of upfront marketing before you can turn this into a passive income stream.
Index funds provide you with a way to invest in the stock market that is completely passive. For example, if you invest money in an index fund that is based on the S&P 500 Index, you will be invested in the general market, without having to concern yourself with choosing investments, rebalancing your portfolio, or knowing when to sell or buy individual companies. All that will be handled by the fund which will base the fund portfolio on the makeup of the underlying index.
Consider refinancing your mortgage if you haven’t done so in a while before interest rates go up further. Or consider leveraging cheap money responsibly to acquire hard assets. LendingTree Mortgage has one of the largest lending networks online, and they will contact you immediately with their offers. You want lenders competing for your business, and get hard quotes so you can pit them against each other.
Refinancing may not be worth it to you, depending on your situation and interest rates, but maybe a reverse mortgage is just what you need. It's typically an option well worth considering for those in or near retirement. A reverse mortgage is essentially a loan, with the amount borrowed not having to be repaid until you die, sell your home, or stop living in it (perhaps because you moved to a nursing home or died). At that time, the home can be sold to cover the debt -- or your heirs can pay it off and keep the home. Reverse-mortgage income is often tax-free, which is another big plus. The amount you get can be delivered in monthly installments, providing very passive and reliable income in retirement.

It was easier recouping the lost $60,000 in rental-property income than I expected. For so long, my primary mindset for passive income was rental income. Having $815,000 less mortgage debt but still generating roughly the same amount of passive income with a much larger cash balance feels great. Further, my passive-income portfolio got even more passive, which is good as a stay-at-home dad to a newborn.
Speaking of selling stuff online, that's another mostly passive way to generate income. You could generate an income stream for a while by clearing out your basement or attic and selling items on eBay or elsewhere. This can be especially effective with collections. If you have lots of games or jigsaw puzzles that are taking up space and not being used, they can be great sources of income. You might reap a lot by selling new and used clothing you don't need.
For a campaign to become viral, you need to strike the right emotional chord with your audience. Ice Bucket Challenge evoked a positive and high arousal emotion as it was funny. By keeping your campaign lighthearted, you will be able to connect with your audience at a human level, which can result in better engagement. If you target the right kind of emotions, the chances of your campaign to become viral will increase.
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. 
With $200,000 a year in passive income, I would have enough income to provide for a family of up to four in San Francisco, given we bought a modest home in 2014. Now that we have a son, I'm happy to say that $200,000 indeed does seem like enough, especially if we can win the public-school lottery to avoid paying $20,000 to $50,000 a year in private-school tuition.

When I started building my architecture-related business in 2008, I made my first dollar through advertising. I’d spent a lot of time and money building the site and getting traffic. Then one day I threw an ad on the site one day, and I made $1.18. Sure, I could find that much under my couch cushions—but that’s not the point! The point is that I was able to build something online, put an ad up, and make money without having to do anything. I learned it was possible, and it motivated me to move forward.
Using influencers in viral marketing provides companies several benefits. It enables companies to spend little time and budget on their marketing communication and brand awareness promotion.[47] For example, Alberto Zanot, in the 2006 FIFA Football World Cup, shared Zinedine Zidane's headbutt against Italy and engaged more than 1.5 million viewers in less than the very first hour. Secondly, it enhances the credibility of messages.[48][49][50][51][52] These trust-based relationships grab the audience's attention, create customers' demand, increase sales and loyalty, or simply drive customers' attitude and behavior.[50][51] In the case of Coke, Millennials changed their mind about the product, from parents' drink to the beverage for teens.[53] It built up Millennials' social needs by 'sharing a Coke' with their friends. This created a deep connection with Gen Y, dramatically increased sales (+11% compared with last year) and market share (+1.6%).[53]
Viral marketing works famously on the Internet because instant communication is easy and inexpensive. The digital format makes copying simple. From a marketing standpoint, you must simplify your marketing message so it can be transmitted easily and without degradation. Short is better. The classic is: “Get your private, free email at http://www.hotmail.com.” The message is compelling, compressed, and copied at the bottom of every free email message.
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.
Vanguard: Vanguard has a minimum of $50,000 and a fee of 0.3%. Rebalancing is done automatically once every quarter and tax loss harvesting is done on a client-by-client basis. We included Vanguard because clients who invest between $50,000-$500,000 have access to a team of financial advisors. Those with accounts over $500,000 will have a dedicated advisor.
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.
In order to build an audience, you need to have a platform. You need to have something worth following and sharing; something that’s valuable to others. And that, of course, takes time. That’s not to say you can’t build a huge audience in a short amount of time. But as much as we hear about the people who’ve succeeding at doing this, we don’t hear about the millions of others who are struggling every day to get just a few more fans and followers.
To start Viral Marketing, companies use ‘seeding’. A seed is planted, it grows, creates new fruit with seeds that subsequently distribute its seeds. That means that a marketing campaign gets a nudge in the right direction; people are actively informed about the new campaign via social media. They’re stimulated to watch the expression. That gives the originator influence over the direction and the result of the viral marketing campaign.
The term viral strategy was first used in marketing in 1995, in a pre-digital marketing era, by a strategy team at Chiat/Day advertising in LA (now TBWA LA) for the launch of the first PlayStation for Sony Computer Entertainment. Born from a need to combat huge target cynicism the insight was that people reject things pushed at them but seek out things that elude them. Chiat/Day created a 'stealth' campaign to go after influencers/opinion leaders, using street teams for the first time in brand marketing and layered an intricate omni-channel web of info and intrigue. Insiders picked up on it and spread the word. Within 6 months PlayStation was number one in its category—Sony's most successful launch in history.
