But you have to admire the virus. It has a way of living in secrecy until it is so numerous that it wins by sheer weight of numbers. It piggybacks on other hosts and uses their resources to increase its tribe. And in the right environment, it grows exponentially. A virus doesn’t even have to mate. It just replicates again and again, doubling with each iteration.
Our spending and saving habits develop over time, and it is because of this reason that they are often hard to change. Economists use a phrase called “propensity to consume,” which suggests how much of additional portion of $1 earned will be consumed by us. For example, if I earn an additional $100 a day and spend 90% of this $100, my propensity to consume will be 0.9, which is often considered a high number. We often fail to change our propensity to consume because our spending patterns are deeply rooted into our psyche.
I love real estate investing, but it requires a lot of upfront capital plus you are going to have to learn to love your tenants (see point 6 below)! Crowdfunded real estate investing gives you a way to still invest in the real estate market, without having to necessarily put in a lot of money upfront. It’s definitely a much more passive investment than owning a flat or a house!
Here's an option that's still unfamiliar to many people but that has been growing in popularity: Lending money on a peer-to-peer basis. A major website for this is lendingclub.com, where investors have earned returns in the neighborhood of 4% or more annually. You'll be lending money to fellow individuals who have had trouble borrowing money through other avenues, and you can spread your dollars across many such folks to reduce the risk.
I first discovered the power of passive income when I was a senior in high school. I started a mobile billboard business where I would rent a small piece of land from someone who had land along a busy highway. Then I would place one of my billboard trailers on the land and rent out the ad space on the billboard. I would usually charge about $300 per month for the ad space, meanwhile I was only paying $50 per month to the landowner for the ground rent. I got to the point to where I had 9 billboard faces and was making quite a substantial income for someone in high school. I really learned how passive income could free up my life… this business is what lead me into investing in real estate.
The more residual income you can build, the better off you’ll be. In fact, it’s said that the average millionaire has 7 different streams of income. By creating passive income streams that generate money while you sleep, you’ll build wealth faster and diversify the ways you’re able to make money – which helps protect you from the loss of any one individual income stream.

I just graduated college in May and was fortunate enough to secure an entry level consulting position that pays 55k/yr (a little less than ~35k after 401K, other benefits, and the lovely taxes that government bestows upon us). I started from “scratch” with my finances and have ~$2.3k in an online savings account. Since starting work a couple of weeks ago, I’ve had an aggressive savings plan (saving around ~40-50% of my monthly income). However, I’m going to become even more aggressive and live off 1 paycheck a month (and save the other paycheck) like you have suggested in many of your blog posts.

​If you pay your bills with a credit card make sure it offers cash back rewards. You can let your rewards accrue for a while and possibly put the easy money you earned toward another passive income venture! (Be sure that the card you select doesn’t have an annual fee or you might be cancelling out your rewards). Check out this list of the best Cashback Rewards Cards.

Thank for this extensive work. When you make extra money you need to think simple. First thing you should consider is whatever you do must be safe enough that you don’t lose your initial investment as well. Also, look at the ways you can reduce your costs. This could be car insurance savings or paying back expensive loans or card balances. Saving is making money as well.
Many entrepreneurs reading this post will realize that they may not have the means to achieve true viral growth (where they have a Viral Coefficient of greater than 1). Rather than giving up, it is worth considering a hybrid viral model. In the hybrid viral model, you make up for the shortfall in customers by acquiring those through some other means such as paid search, or SEO.
However, you should pick a niche and blog about that. If you're launching a money related blog, maybe it'll be about how to make money in real estate or simply how to make money online. Pick the niche and stick to it. If it's a diet and fitness related blog, maybe the niche is the Ketogenic diet, the Atkins diet or some other form of diet or fitness.
What I did: I first identified my favorite places in the world to live: San Francisco, Honolulu, Paris, Amsterdam, New York City, and Lake Tahoe. I then looked up the median rent and housing prices for each city. Then I factored in private education costs for two kids to be conservative given I may not have two kids and public schools are often good enough. After calculating all vital costs, I then did a self-assessment of how happy I was making $50,000, $100,000, $150,000, $200,000, $250,000, $350,000, $500,000, and $750,000. I decided working 20 hours a week making $200,000 a year is the best income balance for maximum happiness. 
That’s a nice read! I love your many tangible ways mentioned to make passive income unlike certain people trying to recruit others by mentioning network marketing and trying to get them to join up and sell products like Amway, Avon, Mary Kay, Cutco or 5Linx. People get sucked into wealth and profits and become influenced joiners from the use pressure tactics.
I don’t really know much about those…I should take a look from a diversification standpoint. If you don’t mind me asking, what do you target for your net effective tax rate on your passive income? Also, I’m sure you’ve probably covered this somewhere, but how do you deal with healthcare? One more dumb question…have you found that you spend more or less money than you anticipated once you retired?
Inspired by you, I started a tax/personal finance a month ago. I figured if it works out, it will create a good side income for me. If not, at least I can use the blog to build my brand as a tax lawyer. Other than that, my current investment portfolio is heavily focused on index funds because of its historical performance and tax & cost efficiency. Right now my dividends income every year is about $14,000. I also have a good amount of unrealized capital gains every year from my investment, though I don’t count the capital gains as my passive income as they are paper gains, at least for now.

What's crazy is that my book income is more than my SF condo-rental income. Yet I didn't have to come up with $1.2 million of capital (the minimum cost to buy my condo today) to create my book. All I needed to create my book was energy, effort, and creativity. I truly believe that developing your own online product is one of the best ways to make money.

You are also free to choose a fund that is based on any index that you want. For example, there are index funds set up for just about every market sector there is — energy, precious metals, banking, emerging markets — you name it. All you have to do is decide that you want to participate, then contribute money and sit back and relax. Your stock portfolio will then be on automatic pilot.
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!
The reason to make use or virality, the ease in spreading and sharing, is however a double-edged sword. We cannot forget that in this type of campaign, a large part of the control falls into the hands of the users, and we risk the message being misinterpreted or parodied. On the other hand, a successful viral campaign can work miracles for your brand’s results.
