Can someone be a good writer without being creative? Can someone be creative without being a good writer?

Yes. “Good” writing comes in all kinds of forms. “Good writing” or “Good writer” are broad terms that change their meaning depending on genre, the purpose of the particular writing piece, and the author’s writing style.

So my answer to your question is yes. Not all writing genres are meant to be creative. The meaning of the word “creative” is again a broad term.

Likewise, writers can be really creative but the purpose of their writing gets lost because they’re too focused on being creative.

Creative writing is something that takes practice. It’s truly an art. It’s really all about balance.
