"People will pay to learn what you know about programming or designing, how to be a better public speaker, and or how to increase sales. How you design, develop and create your e-course will depend on what you teach, how you teach, and the best way for your readers to learn" Zelenko says. Sure, you'll spend some time and money developing your course on platforms such as Udemy.com or Teachable.com, but once you've created it, there's minimal upkeep.
The books are pleasantly organized, customers served, teams managed, etc. The problem (in my mind) is that this is hugely time intensive and easily capped. Income = Time x Value, where Time is a finite resource limited to 24 hours a day (or, more realistically, 12).The way most people address this is to change the second variable. They get a law degree, MBA, or PhD, making their time worth more money. This works swell… but it’s still limited. At some point, you’re that lawyer making $550/hr, but your income potential is capped, as willingness to pay more is at it’s highest, and no new time can be created. What to do?
​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. 

Making legitimate passive income isn’t as difficult as you might think. Some of the best passive income ideas might take a little time to set up but can start cash flowing within a couple of months and will provide a consistent monthly income for years or more. The most important point is just to get started. You make exactly $0 on the passive income sources you never start.
For those willing to take on the task of managing a property, real estate can be a powerful semi-passive income stream due to the combination of rental and principal value appreciation. But to generate passive income from real estate, you either have to rent out a room in your house, rent out your entire house and rent elsewhere (seems counterproductive), or buy a rental property. It’s important to realize that owning your primary residence means you are neutral the real estate market. Renting means you are short the real estate market, and only after buying two or more properties are you actually long real estate.
Obviously, these are much higher than you’re going to get with most other investments. What’s more is that you can choose a plan that matches your investment strategy, whether your goal is Supplemental Income, Balanced Investing, or Long-term Growth. You can also look at different real estate projects and choose for yourself which ones to invest in.
Real Estate: I currently own one rental property in San Francisco which I bought in 2003 (2/2 condo), one vacation rental in Squaw Valley, Lake Tahoe (2/2 condo), and my primary residence. Real estate is my favorite asset class to build wealth because it is easy to understand, tangible, provides utility, and rides the way of inflation. I recommend individuals try and get neutral inflation by buying their primary residence as young as possible. The power of inflation is just too hard to counteract.
Like many, I was first really turned on to the idea of passive income by Tim Ferriss. In The Four Hour Work Week, he describes the system he developed with BrainQuicken, where the marketing, shipping, reordering, banking, and even customer service of the company was on complete auto-pilot. I found this idea intoxicating. The idea that Tim could travel the world learning to tango and staying on private islands while money just accumulated in his bank account seemed like some strange fiction — surely, this isn’t how people actually live, is it?
Writing an e-book is very popular among bloggers, as many have noted that “it's just a bunch of blog posts put together!” You will not only have to make an investment of time and energy to create the e-book, but market it correctly. However, if marketed correctly (through blogging affiliates in your niche, for example), you could have residual sales that last a very long time.
I agree mostly with the real estate advice. I’m looking for ways to take advantage of the condo I own to get up the rent from ~$0.90/ft to the $1.2-1.5/ft that seems more like the range in the same area. I’d have to put in a bit of capital (probably 10k on the low end for just the basics up to 40k if I wanted to remodel the kitchen and 2 bathrooms up to par with the area), so the return is likely there if those upgrades warrant $1.30/ft (given the unit is larger than most 2br/2ba in the area).
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.
When a taxpayer records a loss on a passive activity, only passive activity profits can have their deductions offset instead of the income as a whole. It would be considered prudent for a person to ensure all the passive activities were classified that way so they can make the most of the tax deduction. These deductions are allocated for the next tax year and are applied in a reasonable manner that takes into account the next year's earnings or losses.
