All obvious creepiness aside, an interesting writing exercise is that of obituary writing. Whose obituary should you write? Yours, of course.
Pretend you’re dead. What will the newspaper say about you? How did you go? Freak fishing accident? Accidental decapitation? Who survives you? What kind of memorial service will you have? Something traditional, or will you have your ashes shot into space?
Tell all. Spare no details. Go.
