Holly told me she started writing content in 2011. At the time, she still worked a full-time job but created content online part-time to supplement her income. Over time, she was able to double and triple her rates until she could quit her full-time job to write. These days, she makes bank as a freelance writer and teaches others to do the same via her online course, Earn More Writing.
Sell your eggs. This is much more timely than selling sperm, but for any ladies who want to make a lot of money and don’t mind selling their eggs, you can earn up to $10,000 for a single treatment. The process of selling eggs takes several weeks of injections and a minor outpatient procedure, and may be slightly uncomfortable. The upside is that you make a lot of money in a relatively short amount of time.
There are also some great apps that allow you to earn rewards as well. For instance, Ohmconnect is a free app pays you just for reducing your energy usage.

Viggle is an app that lets you earn points for watching TV, while Ibotta offers cash rewards AND helps you save on groceries.
If you have your own dog or if you’re looking to get some extra exercise, consider offering a dog-walking service. While this isn’t a huge income-earner, you can still earn $50-100 per week just by picking up a few pups.

Creating space for banner ads on your website is another way to generate a revenue from adverts. However for this type of advertising you will need to contact businesses directly and ask them if they would like to advertise on your website. The upside is that you can charge a set amount, or even a recurring monthly fee, to business to promote their services on your site. Using a WordPress plugin like AdSanity is an effective way to manage this type of advertising.
Food. The second word in “Bed and Breakfast” is just as important as the first. Some B&Bs have tried to serve their guests muffins, juice, and coffee in the mornings, but the most successful hosts understand that the breakfast they serve will make a lasting impression on their guests. You can get creative and serve the type of breakfast traditional for the area that you’re in. For instance, if your home is located in the South, then eggs, grits, and biscuits may go over well, while Southwest guests may appreciate a traditional Tex-Mex meal. Whatever you decide, make it memorable and make sure that your guests feel welcome and appreciated. Make it memorable, and they’ll spread the word for you.
Get-rich-quick schemes and fad weight-loss diets are naturally popular because they satisfy the id while also attending to the super-ego. The ego's job is complete when it sees something like this. The appeal of "fast'' stems from the innate desire for instant gratification, so beware of what seems too good to be true (they often are) when you're looking to make money quickly. Be wary. Listen to the conversation deep within the confines of your mind and do your best to tame the proverbial beasts.

Alibaba is a Chinese eCommerce store that matches Chinese suppliers with buyers all over the world. Prices are extremely cheap, providing the possibility of large profits. However, with the potential profits comes more risk. As you are dealing with suppliers in China, if the quality of the product that arrives isn’t up to standard there is little that you can do about it.
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).

E-books represent about 20 percent of all book sales in the U.S. The good news is you don’t have to be a publisher with deep pockets to get in on the action. As a solo internet entrepreneur, you can sell ebooks directly from your own website. You can sell your own works or sell a public domain work. Simply upload it to your website (or seller account on Amazon) and start publicizing it on your social media platforms, on your email list, your blog, website, etc.
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.

Parlay your math, science, foreign-language or test-prep expertise into a lucrative side gig by becoming a private tutor. You can tutor people online or in-person.

You can also advertise your services at local schools and community centers.
– Project Payday is one of those sites that has testimonials of people who have earned thousands of dollars by getting paid to get trial offers. I’m not saying you’ll earn thousands, but it is legit and you can earn some extra cash. They assume that by paying you to do a free trial, you’ll either like the product and purchase it, or forget to cancel the trial and get charged for it. If you can keep track and cancel before you get charged (if you don’t want the product), then this is a great site for making some money.
