The organizing principle behind this grouping, appropriate economic units, is relatively simple: if the activities are located in the same geographic area; if the activities have similarities in the types of business; or if the activities are somehow interdependent, for instance, if they have the same customers, employees or use a single set of books for accounting.
I truly believe generating $10,000 a year online can be done by anybody who is willing to dedicate at least two years to their online endeavors. Here is a snapshot of what a real blogger makes through his website and because of his website. Roughly $150,000 a year is semi-passive income followed by another $186,000 a year in active income found through his site. Check out my guide on how to start your own blog here.
In January 2018, I missed my chance of raising the rent on my new incoming tenants because it didn't come to mind until very late in the interview process. I didn't write about my previous tenant's sudden decision to move out in December 2017 after 1.5 years, because they provided a relatively seamless transition by introducing their longtime friends to replace them. I didn't miss a month of rent and didn't have to do any marketing, so I felt I'd just keep the rent the same.

​Udemy is an online platform that lets its user take video courses on a wide array of subjects. Instead of being a consumer on Udemy you can instead be a producer, create your own video course, and allow users to purchase it. This is a fantastic option if you are highly knowledgeable in a specific subject matter. This can also be a great way to turn traditional tutoring into a passive income stream!
Seeing the residential real estate boom coming, I started buying single-family rentals in 2002. I learned a lot about real estate investing and passive income properties over the next five years. As someone that has flipped houses as well as managed a group of rental properties, the best advice I can offer is to know yourself and how much time you are willing to spend on the business. 

Lending Club went public in 2014 and is now worth about $1.7B. They advertise P2P lending returns of over 7% for well-diversified portfolios of over 100 notes. I’ve personally been able to achieve a 7.4% annual return over the past two years in a completely passive way by investing in A and AA notes. Others have achieved a 10% annual return through relatively minimum effort.
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. 
I just found your site & so far I like what I see. I am 50 years old & will be retiring at the end of Jan 2019. I turn 51 the following month. I will have a pension income of $60,000 per year & an additional $5,400 from a survivors benefit. I was able to save $200,000 in a deferred comp program through my employer & wish to know what to do to generate a passive income? I can leave it in the plan which will generate about 3.5% or invest it. My concern is the tax liability of taking out a large sum from that fund & leaving me less to invest. I do have an opportunity to invest in a bar/restaurant with family (my main concern) that currently generates $120,000 annually for an absentee owner. It would be a 3 way partnership if I did that. I do like your idea of creating my own product such a blog with a goal of $12,000 to $18,000 passive income I feel that may be my best option. Any thoughts or advice would be greatly appreciated.
