Residual passive income involves assets that pay you monthly for little to no work, or from work you did once but no longer do. This income is key to automatically generating wealth over time. Some examples include collecting royalties from books you wrote, selling advertising on your blog or website, or selling digital products like e-books, online courses, online workshops or videos.
Join a startup accelerator: Another great option is to apply to a startup accelerator like Y Combinator, 500 startups, or TechStars, where a group of investors will help coach you, connect you with potential partners, and provide startup cash in return for a small stake in your company. The competition is tough to get into these, so don’t rely on them as your only path forward.
Now, it’s time to plan out your show. If you’re doing an interview-style show, you’ll now want to start getting some guests involved. You can use your existing social network to reach out to people you already know or are connected with on Twitter or Facebook. You can also head to Medium or Amazon to find authors or experts on topics specific to your niche.
I have always subscribed to paying yourself first, keeping debt under control and living within my means. Fortunately my wife and I have always made pretty good money so it was fairly pain free to be successful. We were so fortunate to not have any breaks in our work history which is a huge factor. For those who need to dip into savings to cover a long period of work outage, it can be devastating. I’m now at retirement age, house is paid for, no debt, million++ in investments…. You don’t know good it feels to be able to sleep good at night knowing that you can deal with anything that comes up.
Go hunting or foraging for food. You may need to invest in gear and permits, but if you already have these, this is an inexpensive way to get your own food. If you're ethically against the killing of animals, it's pretty easy to forage for food, depending on where you live. Just make sure to forage only for food whose origin and properties you are sure of. Getting sick or poisoned is never any fun.
Last but not least, you can also earn money online by building an online community, although the monetization strategies you can pursue will vary a lot depending on your goals. You can build a community with a blog, for example. You can also build an online forum and charge people for membership. You could even build up a Facebook group and use your influence there to sell and promote products.
Earnest (refinance your student loans): Same idea as above but on your student loans. There is $1.4 trillion in student loan debt outstanding. When you have student loan debt, it can make it hard to get ahead, invest, or to buy a home. If this sounds familiar, refinancing the debt can not only help you pay it off more quickly, but it can save you money on interest too.
Don't put all your trust in Social Security. While it's a good bet that Social Security will continue to work for the next 20 or so years, some data suggest that if Congress doesn't radically alter the system — either by raising taxes or reducing benefits — Social Security won't be available in its current form. It is probable, however, that Congress will act to "fix" Social Security. In any event, Social Security was never designed to be the only resource for retirees in their later years. That makes it all the more important that you save and invest for the future. 
For non-tech people (myself included), web design can cause a lot of stress. And stress means opportunity. If you have a knack for web design or web development, you should definitely be capitalizing on it. And since it’s such a foreign concept for many, it can be a really lucrative side hustle. You can find all sorts of gigs on Upwork. Also, you need to read this article: How to Make $5,000+ a Month Building Websites Part-Time
Create a killer course experience: With your course validated and in the works, you need to figure out how people will take it. Most course creators choose to host their courses from their own websites. This way, they get all the value of bringing customers back to their site on a regular basis. I host my own courses from a subdomain on my own site so I can easily add more. The course experience is incredibly important as well. And after trying most of the solutions, I highly recommend Teachable—an online platform designed specifically for courses.
