Titles and character names I have no problem with. They seem to come easy, and I never get so invested in one of either that I'm resistant to changing it when necessary. But I recognized that my experience here is not universal. F. Scott Fitzgerald famously was awful with titles, which led to his publisher coming up with things that sound today like Soap Operas: Tender Is the Night, This Side of Paradise, The Beautiful and Damned. I don't recall exactly what Fitzgerald's original title for The Great Gatsby was, but it had something to do with eggs and was hilariously bad.
BUT, I damsure do have big problems with other things, more important things, that many writers find easy and natural, so I ain't bragging here.
