they stuck in some old mind state that I cant understand how they havnt picked up on game yet even though its right in front of them
these people not only get a crazy amount of money from youtube, but they get money from selling shirts on they site, ad revenue on their own site which is basically just their youtube videos

sponsors, etc..
Not everyone can be as popular as a Summit or Lirik or Angry Joe or Golden Glove.. but with a good personality and dedication to it, someone can make a comfortable living off gaming. Key word is dedication.. its not your traditional 9-5.. Someone like Nadeshot/Angry Joe make more money on Youtube than most top end streamers (youtube gives more back, but donations and subscribers to top twitch users can balance it out). But all they have to do is play a few hours, get the footage they need and spend the rest of the day cropping it for they video.
Someone like Golden Glove streams a lot and THEN youtubes shyt

I mean for 10-30k a month id do the same I guess but thats easily a 10-12 hour a day job at this point.
To get that popular, you have to treat it like a job. You take a few weeks off or slack on your schedule, people will move on to the next up coming big streamer.. If you notice all the popular streamers/youtubers have a pretty strict schedule.
and like
@winb83 said, its a young man game at this point for the most part.. If I was 18 and streaming came out, 0 doubt in my head id be big on it just cause I could keep up with a 8-10 hour a day schedule playing nothing but games(believe it or not this is the main ingredient to being successful streaming), but man now im to the point where its hard for me to sit down for more than 2-3 hours AT THE MOST and be done for the day. Im to the age where if I play 2-3 20 minute long matches of ANY game im ready to say "aight I gotta take a break" and then I usually end up on the coli or watching TV and never get back to playing a game the rest of the day..
