Etsy: While Etsy's popularity has declined recently, it's still a great resource for selling handmade items online. No need for complex ecommerce sites or merchant accounts or any sort of automation.

The best part is that you can also sell digital products on here such as poster designs. 

You could also opt to use existing websites for making money. These include both active income and passive income methods.

Again, devote a sizable portion of your time to passive income so that you can slowly build up earnings that will arrive on autopilot without any extra added effort.
