Be your own boss forever, make money with platforms like Ebay, Amazon, and newer sites like depop and Mercari, Gumtree and also good old Craigslist.
The basic principle is go to Goodwill Bin Store, buy something for $0.50 and sell it on Ebay for $10 plus postage.
One of the main risks is losing your Ebay account. So when starting out, take it slow, learn the ropes and put the customer first.
Whether you want to make small or big income you can do it this way and make as much or as little as you want.
