Honestly, I feel like the more I stay away from imageboards, the more productive and happy I become.
There's so fucking much negativity around here that it just brings your spirit down and "muh thick skin" won't do shit for you. I think this is why you rarely see popular content creators spending time in imageboards outside short visits, and the people who tell you to grow a thick skin aren't producing fucking anything.
If I had a "community" outside imageboards, I almost certainly would not come here again for any other reason than checking up on "news", i.e what's happening in the world of comics/videogames/whatever.
That said, I would never pretend like I wasn't here. But I certainly wouldn't sugarcoat it either and pretend that imageboards were "important" for my success. Just because you were the first ones to see what I made, doesn't mean you were responsible for it. I chose to show it to you first. I keep improving all the time and building my concepts even though I rarely post anything related to them here, in fact I produce the most when I'm not spending time here. This place is just a way to spend time and not feel like I'm alone in the world because I don't need friends to discuss shit.
I've asked for help and feedback numerous times in imageboards, but I can't recall many times when I received anything worthwhile in return, except maybe some form of encouragement which I honestly could do without anyway. Getting your cock sucked is much easier in hugbox communities like reddit and deviantart and whatever anyway, so giving imageboards credit for that is kinda stupid.
Being told to "git gud" doesn't build character as much as useless fagtrons like to tell you, it doesn't make you stronger, it doesn't encourage you, it doesn't do anything except build resentment towards this worthless place. Almost every single arrtist can tell when they're not good enough at something, they don't need to be told that, especially when it isn't accompanied by any useful guidance.
Furthermore I feel like I'm better than most of the people giving feedback, because most of the people aren't creators themselves, so they're not capable of giving help in the first place. It's easy for anyone to say when something is wrong, but I can tell that myself. What I need is someone to guide me into the right solution, but people who have little to no skills in the subject can't do that.
