Please note that some of the links below are affiliate links and at no additional cost to you, I will earn a commission. Know that I only recommend products, tools and learning resources I've personally used and believe are genuinely helpful, not because of the small commissions I make if you decide to purchase them. Most of all, I would never advocate for buying something that you can't afford or that you're not yet ready to implement.

This has become a popular business model for online entrepreneurs over the past several years, and will probably just continue to grow in popularity. The best thing about selling online courses is that once you do the up-front work in creating the course and setting up your marketing strategy, you can get paid over and over again for work you do once.
Decluttr lets you sell everything from books to CDS to DVDs to electronics and even LEGO! It's my best recommendation for decluttering (hence the name!) by selling stuff you no longer want or need. With books, you just enter in the barcode or ISBN and they'll give you a value. It takes minutes to find out how much your stuff is worth and you don't have to register or anything to price things.
You can potentially make even more money by offering to handle snow removal in the winter. Shoveling snow is often a homeowner's least favorite job, and there are many homeowners who simply cannot handle their own shoveling because of physical limitations. Typically, snow removal companies charge a flat fee for the winter, no matter how many times it snows. You can offer to remove snow a la carte, or you can copy the standard procedure and charge a flat rate. If you already own a snowblower (or can invest in one), this can help you speed up the snow removal process and allow you to take care of multiple neighbors each time it snows. (A snowblower will also save your back muscles!)
Teaching and tutoring English as a second language is a great way to make money online, not to mention open some doors for you to travel the world if you'd like. While full ESL (English as a Second Language) accreditation is recommended, as long as you’re a native speaker and have the ability to teach, there are people in countries such as Hong Kong or the UAE who are willing to pay upwards of $25/hr for you to tutor them English via Skype. Check out Indeed, Learn4Good and Remote.co for remote english tutoring jobs or sign up on a specialized site like VerbalPlanet or Chegg Tutors.
Retain some control. If you upload photos of yourself, or friends/family with consent, it's worth going for the 'rights managed' licence option – otherwise you'll have little to no control over how your images are used (eg, you could star in an ad for haemorrhoid cream). See Alamy's page on understanding stock image licensing for more on the different types of licences.
If you live in an area where Uber or Lyft operate, why not become a driver? If you're looking to make some short-term cash, you can definitely rake it in by working for one of these popular car-hire apps. As long as your vehicle fits within the specifications of their program, and you have a clean license, you could do this on the side, especially if you're in a crunch for cash.
Most of us are guilty of hanging onto things that we never use, myself included. Take a day and go through all your old stuff and get rid of some of it! One tool that is really helpful for this is Decluttr. You can enter your items barcodes into their valuation engine and they’ll give you an instant offer. Then you simply pack all your items into a box and ship them off for free.
