It depends on what you call “having a job”. Unless you have capital to put to work, there aren’t many ways to make money without actually working.

However there are things you can do entirely from your home. One thing is arbitrage, where you buy stuff cheap on sites with low information, and sell expensive on sites with high information. I’ve got a friend who’s been living off of that for 15 years, he just goes on leboncoin (french craig’s list), buys old collectible shoes and suits from people who don’t know what they’re selling, and sells that on ebay to collectors. I had another friend digging up old saxophones on local markets in Mexico, refurbishing them and selling them to the US. It’s pretty reliable but of course you need a lot of knowledge of a specific niche.

Another classic way is ecommerce / dropshipping. Not in a “get rich quick/easy” way, cause it can be slow and a lot of work to get off the ground, but it doesn’t require a lot of initial knowledge or even a lot of “business acumen”. You try to sniff out products that can be bought low on Ali Express and sold high in your home country. You build your personal pipeline which allows you to quickly put a product on the market and test how it sells. Then you add and drop products until you find some that are worth your time. As long as you’re not sentimental with what you’re selling and drive only by the metrics, this can, in time, turn into a day job that pays okay.
