Writers at all stages of their careers struggle with this, and it's a feeling that holds us back. But, the truth is, there's no reason for a writer to feel inferior. Because the reality is there's no one to feel inferior to.
As a writer, your only competition is yourself, and the only writer you should compare yourself to is the writer you were when you wrote your last story. Comparing your writing to someone else's is actually a pointless and needlessly frustrating activity. You're not that writer. You're not producing the same work.
My job is to be the best Lissa Bryan I can be and produce Lissa Bryan's best work. I'm not tasked with being a better writer than [insert name here] because I'm not writing that person's books. I'm writing mine.
We can learn from other writers. Looking at their work - their style, how they craft a story - can help us improve our own. But we need to recognize that we're all walking our own path. No one else can write your stories, so don't feel inferior to anyone. Do your job and be the best you that you can be, and don't let silly comparisons drag you down.
