A large subset of our society is earning a full-time income by selling items on Craigslist and eBay. You can do this by selling your own items, or you can help sell items for other people and take a small commission. Selling on eBay offers more friction than Craigslist and you'll need to establish solid reviews before you can begin to move high-ticket items.
I also think that affiliate marketing is the best way to go. Especially, niche affiliate networks because they connect a lot of advertisers that fit your theme on one platform. For anyone writing about travel, culture or food I would recommend Travelpayouts since they are the biggest in the niche. They have more than 60 different programs that market different services (Booking and Hotels.com for accommodation, RentalCars and Omio – for transport, Aviasales and Kiwi for air travel, etc). In my experience, Travelpayouts are also honest and easy to use.
Demands on Your Time and Personality. Tech support is a 24/7 business. You’ll likely have some freedom to set your schedule, but you’re virtually assured to have some work shifts that don’t jibe with your lifestyle. You’ll also likely be responsible for some holiday and weekend coverage, though how much varies by employer. Finally, you’ll need to be “on” and personable at all times. If you don’t think you’re capable of maintaining a sunny disposition as you near the end of an eight-hour shift, this might not be the job for you. Internet Marketer
