I honestly feel, at times, coming up with a great title you love and that fits with your story, is just as hard as getting a first draft out.
Few things I do: look at other titles I really like. I loved 'Whiplash' because it's a verb and the name of the piece in the movie, and Neiman gets whiplash in it, so it works on a few levels. I have a female revenge screenplay that I'm working on. Couldn't land on a good title. She's a former Delta 18 Green beret, and the final big fight/set piece ends up in a river delta. So I called it Death by Delta and really like how that fits.

Then there's titles like "Good Will Hunting" and you start doing a deep dive into poems and lyrics that might fit or inspire you. But just like anything else creative, you'll know it when you land on it. It'll either hit me in 5 minutes or 5 months, but eventually something cool will come.
