My most shameful baggage
The best part about writing a memoir is that you already know all the events in the story (so far). The characters developed in real life and the setting has always been around you. The hardest part of memoir writing is the emotions that come along with remembering and going over your life (over and over and over again).
Memoirs do not document your entire life. The purpose of a memoir is to relay a PART of your life. The memoir is a story of themed events that got you to a specific time and place in your life.
Try your hand at writing your memoir of the DAY leading up to your most shameful baggage and the immediate aftermath.
