For this you do not need a degree, I did it growing up and made hundreds if no thousands of dollars! So there are a couple of different ways you can do this. Let's start from easiest to hardest. The number one easiest way is plugin development, basically what you do is you build plugins/mods for video games, typically the game is multiplayer, and it is the server owners that request the mods. I charged anywhere from 50 to 100 per mod and would only take me a couple of hours to do, and at the time I was not nearly as advanced as I am now, so you can as well. You can go into google and type “… plugin request paid” and you will find various forums with people looking for developers. The second way is to build a website or online business, this one is a lot harder than the one before this as it takes a lot more time and effort, but it can be very rewarding. A good website can make thousands of dollars every month, and you only have to write one or two excellent articles. Secondly, this type of business works in your sleep! The third way is to become an influencer, you can build small applications and make videos documenting them. They do not have to take very long to do or be particularly invest for the avid programmer as to people who do not code, every thing about programming is interesting. You can also out source your skills on websites like Fiverr or Upwork.
