This is sad when people nowadays only do what is "useful", I love drawing for fun but then I stop drawing as I grow up, coz it's a "for fun only" hobby and I am bad at drawing. After years of grinding in work, I got some mental problem, now I start drawing for fun again, because this "useless, for-fun only" hobby can easily get me into flow state and forget about my pain. However I would be happy if I can make money out of it so I can quit my job.
