If you’re willing to take on some risk and have the heart of a true hustler, you can make extra money online doing commission-only sales for startups and other businesses. While you won’t be getting a regular salary, with the right sales strategies and skills as an inside sales rep, you can make decent money for each sale you bring in. And because you’ll most likely be working with startups, if you can negotiate a little equity you could profit big time if you're pitching a solid product and the startup succeeds.

Blogging is something that requires patience, persistence and discipline. It may mean writing everyday for over a year before you really start to see any money from it. There are exceptions to the rule, but from my dealings with other bloggers, it seems to be pretty common to spend one or even two years building your blog, your brand and your authority, before making any serious amount of money.

WordPress is a great free content management system that you can use to start a website and begin publishing articles immediately. Use your articles to draw readers in, then present your ClickBank affiliate offer within the article. You may also want to develop a newsletter for your own website and use it to promote your ClickBank offers to your audience as often as possible. (See: How To Monetize Your Website.)

I came across this ClickBank university, recently during the summer of 2017. I am not sure if it was the updated version but, I am glad you reviewed this product. I almost signed up with them, thinking that they would actually provided answers to building a business. For some reason, I changed my mind. Probably because, I knew it had a catch to it somewhere.

Glad to hear it! Absolutely, CPA credentials are still extremely valuable—though it definitely takes a time/education investment in order to secure those credentials. Worth it though? I’d say hell yes, if the field interests you. Even the side income you could make by doing taxes for people just a few months out of the year can be lucrative here in the U.S. at least.
Mechanical Turk: Amazon's Mechanical Turk is a resource for doing human-intelligence tasks, or as the site commonly refers to them, HITs. You get paid a very small fee for any given HIT and you'll need a good deal of volume to make a substantial amount of money.
