But, you don't need to go further than that. You can simply write it and publish it and collect the income. That's all. Send out a couple emails to your list (if you have one) or post it on social media, and there you have it. Passive income. Now, the amount of income you receive depends on the quality of the book you've written. How well did you craft the message? How targeted was the information to your audience? It counts.
If you are a photographer looking to diversify your income stream, putting together styled stock photo packages can be lucrative. For example, a package of 15 wedding-themed stock photos for $10. You can then market this to any bloggers or businesses who are in the wedding business for their use (photos of different engagement rings styles are super popular). Through this method, it’s possible to make a continuous stream of income off of photos you’ve taken once (similar to a licensing deal).
Article writing is one of those things that isn’t at all glamorous, and few people will get excited about it.  With that said, it’s one of the easiest ways to set up your passive income stream.  To give you some perspective, I wrote about 120 articles late last year and have hardly written any since then.  Since that time, my articles have earned me over $700.   I continue to earn $70-90/month without having to do any additional work, which is something I look forward to every month.
Hi Sam! I loved your sentence, “There’s so much information in my head that I need to write it down or else I might explode.” That’s exactly how I feel! I never thought of myself as a writer, and especially not a blogger, but recently I’ve started dabbling in it and it feels so nice to get everything out! I’m dedicated to helping others succeed with personal finances, and there are plenty of “how-to” sites, but it’s important to get people thinking and motivated to prepare, plan, and save!
After these tenants move out, I'm thinking of just keeping the rental empty with furniture. It sounds stupid to give up $4,200 a month, but I really hate dealing with the homeowner association, move-in/move-out rules, and maintenance issues. Given that the condo doesn't have a mortgage and I have to pay taxes on some of the rental income, I'm not giving up that much. The condo can be a place for my sister, parents, or in-laws to crash when they want to stay in SF for longer than a week or two.
It also shows clearly why the median and the mean of the asymmetrical log-normal, even more so for a power law, differ and represent threshold conditions. One does not have to get into the mathematics to see that averages in an asymmetrical distribution do not convey the same degree of the “typical investor behavior” that they convey in a symmetrical distribution. How do you optimize your practice for the average investor if your own investor income and wealth data follow such an asymmetrical distribution?

An obvious example is over exposure to bank stocks, which have been excellent investments for over a century.  Though a foundation of most portfolios, bank stocks do involve more risk at certain stages of the economic cycle than many realise.  Being less exposed to bank shares in the last few months could have preserved some capital.  So, a more diversified approach can help mitigate some of these risks.
