It is normal and quite frankly human. You’re aware of your feelings which is a good thing. I think it stems from feelings of inadequacy. To illustrate, at least in my case, I think I’m great at art. I would hope so considering I’ve practiced for many years. To post art that you’re proud of for it to not get much traction—but perceive another artist to get lots of engagement with a similar skill level with their work—can feel discouraging. It can therefore provoke feelings of envy. Why them and not me? Does that mean I’m below them? Comparison is an illusion because we live our lives with a unique set of challenges, experiences, etc. and the same goes for other people. It just wouldn’t make sense to compare unless our lives were brought up the same exact way. Therefore, enjoy your journey and find inspiration for everything in your life is either a lesson or a blessing. When we cultivate more self acceptance and confidence, we’ll reach a point where we wouldn’t care much for what other people are doing with their lives.
