There is a trajectory of mental states from the beginning writer toward the seasoned, thick(er)-skinned writer. I think that development along that trajectory includes getting beyond the innocent hubris of “My writing is great! People have always said so!” and moving toward the knowledge that all good writing takes work and generally benefits from a variety of voices giving constructive feedback.
Like the child who is always praised and never challenged, we do no service to ourselves by glossing over things we need to work on. I ought to know. I used to be one of those innocent hubris writers. I hope I’ve moved beyond it.
I sure have a few calluses.
