People often hold back from creating, asking "If I did X, would it be good?" Like, "If I did a comic about aliens who invade Earth to make and sell salsa, would that be good?"

Art is about how something feels. We don't "think" as we're enjoying art. The only way to know if a creative idea is good is to make it and see how it feels. The best ideas can end up not working, and a tiny weak idea can become something amazing.

How can you know if something is good or bad if it doesn't exist?
