My 10-year-old son brought home a book from our park’s free library box. It was a biology textbook – teachers edition. He said it looked interesting and hey, it was free (having no idea you could sell it). I scanned it in my Amazon seller app and realized it was worth around $150. He was so excited. We listed it for sale for $130 and it sold! Going to tell him, he just made $130!
Fiverr: Israeli-based Fivver was started in 2010 by Shal Wininger and Micha Kaufam. It's a great resource for selling just about any service online. You can offer gigs as low as $5 but also get paid much more for upgrades and add-ons. There are plenty of providers earning 6 figures on Fiverr so it's definitely a worthwhile cause for generating a healthy income. Just ensure that you provide some serious value. 
While Etsy is fantastic for handmade goods that you’ve already created, if you’ve got killer designs that would look good on phone cases, t-shirts, or even wall hangings, pillows, and duvets, you can sell them on Society6 without paying anything to start. Society6 lets artists upload their designs and create their own shops where they choose what products their designs can be used on. That means one design can be used to make a whole range of awesome products that are printed and shipped on demand whenever someone buys from you. With top creators making thousands every month just from selling their designs.
Another seemingly free site you can make money from is Wikipedia. People who say it’s easy to edit Wikipedia have clearly never tried editing Wikipedia – it’s a pain. Thankfully it’s a pain for companies as well, so many of them are willing to pay editors to assist them in the editing process. You’ll become a bounty hunter in a way, choosing your own lines to cross and keep. If editing is something you like to do, and you’re willing to put in the work it takes to learn Wikipedia’s dispute process, roll up your sleeves and try this one out.

Promote products that are stepping stones to products you will create in the future. This is a bit more advanced, but is a great way to think ahead. Amy Porterfield suggests thinking about the first thing your followers will need in order to get started with what you provide. For example, I teach people how to blog, so the first thing they need to start a blog is hosting. That’s why I am an affiliate for hosting.

Now you’ve got many different options to start earning online. If you saw something that really interests you, try it out and learn more about it. If you’re really wanting to make a full-time income online, you need to be dedicated to learning how to do what you want to do. There are tons of free resources out there. You just have to search for them!
If you have a passion project, Kickstarter may be exactly what you need to get it off the ground. Celebs like Zach Braff and Melissa Joan Hart have used this site in attempts to fund their movie projects. Some crack dealers in Canada inspired a “crackstarter” campaign from Gawker for pictures of the Toronto mayor smoking crack with them. All you need is a dream, a goal, a budget, and a great pitch to convince people to come to the site and donate to your Kickstarter campaign. Panhandling isn’t dead – it’s gone digital…
Running a coupons website can be very lucrative. Find a coupon niche, select a WordPress coupon theme, and then display relevant coupons on your site. When your audience uses the coupon codes or discount links, you will earn an affiliate cut for example you could set-up a site dedicated to iHerb Coupons or add a page to your website with Web Hosting Promo Codes. Coupon websites are quite high maintenance as they need to be constantly updated with new offers. However, if you build up an engaged audience and allow them to post coupons and discounts they have found themselves, then quite quickly your workload will reduce.
