Recognize what most people think is “bad” writing really is just “unfinished” writing. In other words it hasn’t been revised (or revised enough times) to create a polished, professional document.
Although the words revising and editing are often used to refer to the same thing, rewriting your first and subsequent drafts, in the publishing world revising is what the writer does and editing is, well what an editor does. The writer revises until they are satisfied and sends it to the editor (there are multiple kinds of editors, here we will simplify it to just the editor) who “edits” by checking for structure, style, grammar, spelling, and other problems. The editor may work closely with the writer or they may work separately sending each draft back and forth until both are satisfied.
If it is not a formal publication then really it doesn’t matter what you call it, revising or editing, so long as you go through the various tasks of rewriting your work.
