its much stressful to play competitively, live in insecurness :\ and what happens when its going to end? You cant apply for a job as "i was a professional gamer" :D
I have a good job and occupation, which is more important i think. I dont have to worry about money and i'm happy to not stress about idiotic team mates, who dont want to put time into it, to become better :)
I was very passionate about playing between the age of 14-19, but then i realised, its better to move on :) and that was the right choice :D atleast for me
and its better to get the same salary (or higher) for 30 years, then get a lot for ~5, then almost "nothing"
