Don’t base your confidence/self-worth on what you do/what you’ve done. We live in a highly competitive, validation-seeking world. The push to be better than others, to win, and to focus on appearances can be addicting and dangerous. If you let it, competition will drive you to points of depression, obsessive mistrust and creative lack. I’ve seen many go down this path. I almost did. You are more than your creations and your art should always be an expression of you, not an egotistical bubble.
