Your protagonist sits down at a desk and begins penning a letter to his or her younger self. What would they tell their past selves? What regrets do they voice? What lessons have they learned? How have they changed? Write this imagined note yourself, in your protagonist's voice.
A talk show is scripted to promote the guest and discuss topics with which the guest is comfortable. Imagine your protagonist on the Ellen Degeneres Show (or The Late Show With Stephen Colbert - whichever show you're familiar with). What questions would be asked of your protagonist? What funny anecdotes would your protagonist share? Write down the reactions of both your protagonist and the host.
