On Craft and Complaining (and other negative emotions) - A Short Story · 8:38pm Feb 20th, 2016
Complaining feels awesome. Airing regrets, getting righteously angry about them and just having an all-around tantrum is amazing. Plus, it's good to get it out and not bottle it up. This is still true when you're feeling in a slump with your art (be it wordcrafting or artworking or other-ing).
So yes. Let it out periodically so it doesn't taint your body, your mind, your soul, or your craft.
