Matched Betting (not available in the USA) enables you to gamble (nearly) risk-free. I say nearly as there is always room for error! It involves placing bets on all outcomes of an event, using free online bets given out by the Bookies. Although it may take a while to get your head around the concept, Matched Betting can make a substantial addition to your monthly income.
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.

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.

Manage social media for businesses. If you have a knack for social media, you could potentially get paid to manage various platforms for others. Many businesses are too busy running day-to-day operations to stay on top of their Facebook, Twitter, and Pinterest accounts – and will pay someone with the knowledge and time to do it for them. To find these jobs, ask local businesses and check sites like UpWork.com and Problogger.net.
Diversify your business. You may use a lot of trial and error to determine which business ideas work the best, but doing so will let you discard methods and ideas that do not work in favor of ones that do. Try new business ideas or products to sell as you go. Don't put all of your eggs in one basket. Ten products that make $100 per month are more profitable than two that each make $300. If you seem to cap out at a certain amount each month on one product, add another to your repertoire.
If you're not self-employed and work for a company, find out if they have a retirement plan. If you're lucky, employers will sometimes match contributions you make into a retirement fund. Retirement plans also often have the benefit of being tax-deferred. The longer you get to keep your money (and make interest on it) the better. It's never too early to start planning for retirement.
This has become a popular business model for online entrepreneurs over the past several years, and will probably just continue to grow in popularity.
