Today, if you're at all serious about generating a full-time income (and more) from your online activities, then you need to focus on passive income as opposed to active income.

If you have a knack for a certain subject and live near a college, consider offering up your brain power and teaching skills for some quick cash.

Even if your car rarely goes unused long enough to rent it out to a visiting driver, you can still potentially “rent it out” by turning your vehicle into a rolling advertisement.

Generally, your program will last anywhere from 6 to 24 months, and you get paid for following your normal driving routine.

Ever since the idea of online auctions came into existence, the online selling market has been on the rise. Many are interested, but don’t know how to get started. There are still all kinds of ways to make money by selling online, whether you’re selling what you already have or buying and selling like a store. Before we get started, here are a few general tips when selling anything online:
You can make extra money left and right if you just know where to look. If you like to ‘tinker’ I’d suggest going to the DIY section on Pinterest. You can find thousands of projects there to make, and you can sell them at a nice profit. You can make 20, 30, or 50 bucks at a time, in real money. Not the ‘get rich online now!’ stuff you see around. I make old teapots into lamps, or old shirts into aprons and sell them locally on Kijiji or Craigslist. It’s totally doable. 
Mechanical Turk is Amazon's take on micro-jobs. These are small miniscule-jobs that you can do for other people, which they call HITs, or Human Intelligence Tasks. These are super simple tasks that anyone can do. Some examples are listing off some URLs with certain kinds of images for one cent, or recording a few phrases with a microphone for 6 cents.
Gazelle. If you have an old cellphone or an Apple device, you can sell it here. The website will give you a cash offer for your device. If you agree, you'll be sent packaging materials. Gazelle pays the shipping costs, and you wait for a check in the mail, a gift card to be sent or cash transferred to your PayPal account. You may not make a fortune, but it's better than letting an unused device collect dust on a shelf – and far better for the environment to sell it than toss it in a landfill.
Learn then selling guidelines. Each marketplace has guidelines that define what you can and cannot sell. State and federal laws also impact what items are prohibited. In general, you cannot sell alcohol, weapons, service contracts, animals or event tickets. Also, while not always prohibited, you may find restrictions on how you can sell items in some categories, such as art, gift cards and coupons.[27] eBay, Craigslist and Amazon publish these guidelines on their websites.
Whether you're looking to make some fast cash, or you're after long-term, more sustainable income-producing results, there are certainly ways you can make money online today. The truth is that making money online isn't as difficult as most make it out to seem. It does require some discipline. Sure. Without discipline, you'll find it tough to make a buck both online or offline.
