I feel that way a lot. Then I make myself take a look at what other people are posting, and notice that sometimes even then, there are comments thanking them for sharing. I tell myself, if someone was glad to see this more inexperienced artist's work, wouldn't maybe someone be glad to see mine?

And at the very worst, it makes me not feel like I'm somehow pushing my shitty art on other people as much. If someone else pushed their art out there who was worse than me, then I'm not the biggest art burden around.
