the problem is most authors/artitsts who self insert do so in one of two ways.
>put themselves into the story as the most perfect, wonderful person, refusing to acknowledge any of their real life flaws or issues, and/or failing to give their self insert flaws or issues. >insert themselves into a pre-existing character, often erasing some or all of that character's actually history, personality, and nature, and substituting their own.self insert fiction works when you remember that your self insert is a character in the story, and thus bound to the story, and required to be a good character. self insert fic fails because most who try it are incapable of recognizing that fact and instead warp everything to fit a flat, uninteresting projection.
