I used to be jealous of twitch streamers, then I realized what it takes to earn a "living" and said fuck that.
Most popular twitch streamers had been streaming for years before they got an audience big enough to earn a living from streaming. Most streamers who solely stream for a living stream 60-70 hours a week and stream one main game. If they dont feel like playing that game, are exhausted, etc. too bad. If they play another game on stream they lose a lot of their audience. I see professional streamers talk about how they dont want to be online or arent having fun but they have no choice. Oh and you dont get a break either. Take a month off from streaming and you just tanked your income.
Turning playing videogames into a full time job would make me hate videogames, and thats the last thing I would want.
