It's hard, in a way. With art, but also with games in general. I still struggle with a kind of lack of confidence imposter syndrome complex when it comes to publishing and showing my games. I look around and see some incredibly professional, incredibly polished efforts that are other people's first games. I've been doing this for years and often feel that what I make doesn't measure up. But when I show my games I usually get a pretty positive response, especially in person. One's "crappy" game might be more interesting and compelling than they think. That being still I have had some critical and even downright rude responses. I know it's part of the process but it can still be really demoralizing and I tend to take it as a personal failing.
I'd like to say "just do it" but that really is something that's not so easy. If I have helped in some way than that's great, I really love to see what other people come out with even if they don't think all that much of it.
