It’s one of the oldest and most proven ways to make money – buy low, sell high. The buy low part comes from searching garage sales, estate sales, and even thrift stores to find items that are in good condition (“gently used”) but selling well below what they would if they were brand-new. In this way, you might be able to acquire an item for \$5, and later sell it for \$50.
There are many ways to get people onto your list. Lead magnets are one such resource. For example, you can build ebooks, checklists and cheat sheets. But you can also do content upgrades, such as PDF versions of an article with added resources in them, four-part video training series, and more. Think about your audience and what you can offer them to better serve them, then treat them with some respect and you'll eventually reap the rewards.
Market your course: The beauty of using a course to make money online is that you can continue to sell it for as long as you’d like. Look for niche communities on Facebook, LinkedIn, or Reddit that might benefit from your content. Guest post on relevant blogs and sites. Look for anywhere you might be able to get in front of the right people. With just a few hours a month you can continue to generate sales.
How much you can earn: I personally earned over \$650,000 last year from my blogs, but I do this full-time and have put in 5 years of work to build it up to that.  If I remember right (it’s been a while!), I earned \$35,000 my first full year.  We teach people how to replace their full-time income within 24 months in our Project 24 program.  We even outline how to do it in our free webinar that you can watch here.

4. Calculate how much passive income you need. It's important to have a passive-income goal — otherwise, it's very easy to lose motivation. A good goal is to try to generate enough passive income to cover basic living expenses such as food, shelter, transportation, and clothing. If your annual expense number is \$30,000, divide that figure by your expected rate of return to see how much capital you need to save. Unfortunately, you've got to then multiply the capital amount by 1.25 to 1.5 to account for taxes.
A lifestyle blogger writes about their everyday life, hobbies, and interests. From fashion, beauty tips, and male grooming, to food, restaurants, and travel, anything that you experience can be blogged about. And famous lifestyle bloggers can make big bucks. Once you have built up a following, there are many ways to make a profit. Add affiliate links to your website, promote sponsored services, create your own product range, and much more.
Mow lawns or plow driveways. If you’re willing to mow yards or shovel or plow snow in the winter, you could easily start your own snow removal and lawn mowing business on the side. While you can usually find work by reaching out to your local community via word-of-mouth, flyers, or online message boards, the website Plowz & Mowz allows you to set up an online profile and reach more customers in your area.
Speaking from our own experience, you can’t be a passive McDonald’s franchisee. Every McDonald’s potential franchisee will need to complete at least thousands of hours of training before he/she would be approved to acquire a franchise and only if he/she has the financial resources to acquire a franchise. It could take years before one would get a single store franchise. Until the franchisee eventually has acquired multiple stores and established his/her own management team, the franchisee would have to put his/her nose to the grindstone and work his/her ass off every day. I won’t call it a passive investment by any stretch of imagination.

Clearly, there's a lot of demand on Amazon, and if any product is going to sell, it's going to sell well on Amazon. But the goal here is to source the right products that will easily sell at the world's largest online retailer. Generally, products between \$10 and \$50 sell very well here. Just be sure to do the right market research before jumping on this bandwagon.
First off, I’m a blogger so it seems wrong not to mention it, but more importantly, it’s a legitimate way to make money. It’s quite possibly the least straight-forward way on this list, but it’s very doable and it’s also quite possibly the funnest way on this list. I love blogging and I know hundreds of bloggers who feel the same. So let’s talk about making money blogging and what it really means.

Tools & Resources: I’ve written a pretty comprehensive guide on the best web design software that covers both free and premium software packages. If you’re serious about becoming a web designer, then I recommend purchasing the full Adobe Creative Cloud Suite. At \$49.99 per month, this is probably a bargain considering what you can achieve with this set of tools.
A fitness site can have numerous revenue streams. Create healthy eating plans and recipes and lock them away as premium content. Promote and sell a fitness training course, eBook, or a series of videos. Or advertise your own personal fitness services on your site. Topfithub is a good example of a fitness site with decent video content alongside product reviews.
If you have an empty room, unused apartment or vacant in-law suite, consider renting it out on Airbnb or another vacation rental site. Tourists will book your accommodations through the site, and you'll pocket a portion of the rental fee. Before you rent, however, make sure you understand any rules or regulations in your municipality, restrictions from your landlord and gaps in your insurance.
To get started with side hustling, let your friends and family know about your desire for more work. Your network is your net worth in this regard, and can play a powerful role in helping you secure more gigs. It can be surprising how much your network can propel things further simply by asking. But you have to take the first step and ask! Send out personalized emails and post on social media.
Could you make an extra \$200 per month? Sure. How about an extra \$1000 per month? How would that change your life? To most, it would make a monumental difference. But what if  we were talking thousands more per month or even tens of thousands more? How would that alter the trajectory of your life? Clearly, you can make money on the internet. You just have to decide how much of your time it's worth.

Etsy: While Etsy's popularity has declined recently, it's still a great resource for selling handmade items online. No need for complex ecommerce sites or merchant accounts or any sort of automation. The company takes a commission of every sale and charges a small listing fee per item. But many still use Etsy as their primary source of income. The best part is that you can also sell digital products on here such as poster designs.
