Buy and sell domain names. If you’re good at finding popular yet undiscovered domain names, you can make some cash on the side by buying and reselling websites. Think of it as digital real estate speculation. Domains are available on GoDaddy.com for as little as $2.99 per year, but are sometimes resold at far higher prices: According to Business Insider, the site MM.com sold for $1.2 million dollars in 2014. Once you find the perfect domain name to resell, you can market it on Flippa.com for a flat fee.
There’s plenty of work and clients to be found. If you know where to look. To start, you need to know if there is enough demand for your skill to make it worth the effort to go out looking for work.

If you're unfamiliar with the concept of arbitrage, here's how it works. Wikipedia describes an arbitrage as effectively, "the practice of taking advantage of a price difference between two or more markets: striking a combination of matching deals that capitalize upon the imbalance, the profit being the difference between the market prices." Clothier was able to identify arbitrage opportunities in the grocery industry with precision. 
I used to have fun doing surveys while I watched TV. I was choosy about the companies I used and I never paid to sign up for any. I got about $25 in free BlockBuster movie coupons, cashed out about $25 from another site and did an in house project trial where a company sent me to full size body lotions to use and record information about. I had fun, felt like my input was improving the business world, but I wasn’t looking to get rich quick, just earn a little bit in time that typically wasted. Some survey companies pay very little, others pay better. Of course, it is not fair to the businesses conducting the research to lie in order to qualify for a survey and they certainly deserve honest and thoughtful answers to their questions. The companies I worked with told me how much the survey would pay and how long it would it would take. Research for the reputable companies. 

Great article, I have tried a few over the years. I had a side business cleaning offices for years. It did great, but I hated never being able to take more than 3-4 days vacation, so I eventually gave up. I tried MTurk, but if you multiplied my earnings on an hourly basis, it was a little over $6/hr. My blog is much worse, probably less than $0.25/hr.
I have always subscribed to paying yourself first, keeping debt under control and living within my means. Fortunately my wife and I have always made pretty good money so it was fairly pain free to be successful. We were so fortunate to not have any breaks in our work history which is a huge factor. For those who need to dip into savings to cover a long period of work outage, it can be devastating. I’m now at retirement age, house is paid for, no debt, million++ in investments…. You don’t know good it feels to be able to sleep good at night knowing that you can deal with anything that comes up.
