If you become disabled for an extended period of time, disability insurance can provide financial protection. Disability policies pay benefits in the event you're unable to work at all ("total disability") or can work only some of the time ("residual" or "partial disability"). It's important to consider the different types of policies and their costs, so that you'll be able to select the coverage that's right for you.
I wonder what the avg number of hours/week (over a year) would be for something to be considered “passive income”. To me, it’d be under an hour a week. If I was able to earn money from something with that time investment, the hour a week would be mostly a time investment in checking on things that it’s still working and setting the course back on track.

As soon as you build a significant community of followers, you need to keep interacting with them on a regular basis, through comments, social media, or your site’s forum if you own one. Ultimately if that part is not interesting for you anymore, you need to hire people to do it, or find moderators, etc… to do it for free. If they do it for free, expect them to leave regularly, so you have a constant job of “hiring” ongoing.

Not exactly, even though that’s what passive income pushers would have you believe. No, once your site goes live, you need to perform various marketing tasks like promoting your posts and interacting with people on social media, commenting on other blogs, and seeking out new promotional opportunities. Oh and any good blog out there isn’t just preloaded with content and left to stagnate. No, you actually have to write new posts, too. And even if you hire someone to write the post for you, it’s you who has to edit them, schedule them, and oversea the whole operation. All of these things are not passive at all.

Investing in rental properties: Another form of real estate investment, rental investments (i.e. becoming a landlord) could steer you down the passive income path of steady monthly rent checks that you can use to pay off a mortgage loan on the rental property. After the mortgage is paid off, those monthly checks go right into your bank account -- potentially for years to come. 

​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!
In the past, most people wouldn’t have considered selling software to be a source of passive income, but I believe that’s changing. Thanks to tools like Bubble, creating simple web or mobile apps is easier than ever before. You can do a lot without knowing how to code or hiring a developer, and in the future, I think that’s only going to become more and more true.
As a private lender, you can lend to anyone in your social circle. For example, many home rehabbers need access to a source of capital they can tap into very quickly in order to fund the initial purchase of their properties. You can partner with a rehabber who uses your capital for a short-term in exchange for an interest rate that is mutually agreed upon.
Also, I know from my personal experience that when you only do something because you think it’s a money-spinner you end up nearly killing yourself to get the idea over the line.  I remember creating a careers advice site that bored me to tears.  Every word I wrote, hurt a little.  All 200,000+ words!  Do not put yourself through this pain.  I know I won’t ever again.
