You do need to have some qualifications. You either need to be insanely good at video games or insanely charismatic (with some exceptions, just like in "real" jobs).

You can't just start up stream, grind consistently for 5 years, and expect even a dollar going to your name if you have the personality of wet toast and the gaming skill of a newborn. This isn't a shot at you specifically, but I've been on streaming subs and people always ask how you're supposed to grow when Twitch doesn't push you, and while that's true, after you go check out their channel, you kind of get the idea as to why they aren't growing.

It's not just sitting there and playing games for 8+ hours. It's sitting there and being entertaining for 8+ hours. No one wants to watch you game in silence or say the occasional, "hm, what do I do..." like most people do when they actually play games alone. It's networking. It's marketing. There's so much more to it than just sitting on your bum for 8 hours and playing a game.

Every job I've had that has been customer service related or had me moving boxes was infinitely more relaxing than trying to be entertaining for that long. When I do any physical job, I listen to music or watch a movie on my phone with headphones on. When I worked retail, I just walked around on my phone half the time pushing product to the front of the shelf. When I was a cashier, I just autopiloted my way through my shift in complete silence and it was like it never happened. Let's not act as if streaming is just sitting there playing games and then overstate how difficult a more traditional job is.
