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. 
Double check yourself, before you double wreck yourself. Make sure everything you send to a company, whether a résumé, an email or a portfolio, is good to go. Double check your grammar and wording, and for God’s sake use spell check! This is especially important when it comes to the company’s name. Don’t spell their name wrong and be sure to type it how they type it (e.g. Problogger, not Pro Blogger).
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.
Mistake #5: Promoting a lot of affiliate products instead of just a few. Once you start affiliate marketing, you realize how easy it is to share affiliate links. Instead of becoming an affiliate for a lot of different products and sharing them liberally, I recommend concentrating on just a few and sharing them intentionally. It doesn’t seem as spammy, plus you can be sure the products you do promote are closely aligned with your brand and message. Deep is better than wide.
Before I share the strategies that I’ve used to generate over $100,000 in affiliate commissions per month at this point, there are two extremely important rules I use when promoting products that are not my own. You don’t have to use these rules in order to become an affiliate or be successful at it, but it’s what has helped me grow my affiliate income tremendously over the last couple of years:
