While you could launch a regular business selling someone else's products, you could also invent your own product, like billionaire fitness pioneer, Howard Panes who teamed up with Ab Roller creator, Don Brown to create the Stealth, a fitness system that gamifies core workouts. While businesses based on inventions might seem more complex to create, they do present attractive investment opportunities as depicted on popular shows like billionaire, Mark Cuban, and Daymond John's, Shark Tank.
You can set up a website, gradually build up the content (articles, videos, podcasts, etc.), then eventually monetize the site through advertising, affiliate marketing, or even the direct sale of specific products or services. Even better, you can generally find whatever services and technical assistance you need online and free of charge. Later on, when your site develops a reliable cash flow, you can begin working with paid providers who can take your blog to the next level.
Double check yourself, before you double wreck yourself. Make sure everything you send to a company, whether a résumé, an email or a portfolio, is good to go. Double check your grammar and wording, and for God’s sake use spell check! This is especially important when it comes to the company’s name. Don’t spell their name wrong and be sure to type it how they type it (e.g. Problogger, not Pro Blogger).
Try Uber EATS or DoorDash. Uber EATS offers part-time work that’s similar to driving for Uber or Lyft. Instead of picking up passengers, however, you will pick up food orders and deliver them in your area. Pay works similarly, letting you earn a per-job rate plus tips. Door Dash works similarly, letting consumers order food from restaurants and connecting drivers to pick up and drop off their meals.

Be a mommy (or daddy) blogger. If you haven’t used your free time between changing diapers, washing clothes and shuttling kids around to hop on the blog bandwagon, it’s worth considering this potential source of income. And just because you’re a parent doesn’t mean you have to write about parenting issues. In fact, given that there already are so many blogs about life as a mom (or dad), consider writing about another topic about which you are passionate. The more original, entertaining and informative you are, the more likely you’ll gain followers – and you need an online following to make money.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
What these opportunities typically turn up to be is a pyramid scheme. You pay a fee to signup. You then receive a flyer saying how great stuffing envelopes is and list of names and addresses to mail said flyer. IF those people pay that signup fee so they can mail that flyer too, you get paid a small referral fee. ONLY if they take the bait do you get paid.

How much will you make? I think my best month with Google AdSense was almost $5,000 over the last ten years. That amazing month blew my mind since it was actually near the beginning of my blogging journey. When you go from making zero to $5,000 in a month, that will rock your world. For me, it also got me even more excited because I knew there were other ways to monetize.
