• Free of preambles—They start at the flashpoint—the moment when conflict ignites tangible action that drives the story forward.
• Scene-based—They frequently take place in one run of time, without jumping around.
• Observant—They tend to feature not the “I” but the “eye.”
• Insightful—Like a flashlight illuminating a dark corner, they explore something that provoked an insight.
• Specific—They stick with concrete, observable events and actions rather than abstract concepts.
• True—As a subgenre of creative nonfiction, Flash Memoir must uphold the nonfiction contract that what is reported actually happened.

• At its most basic, a micro-memoir is written in sentences, drawn from personal experience, and strives to create a world in as few words as possible.
• A true hybrid, the micro-memoir strives to combine the extreme abbreviation of poetry, the narrative tension of fiction, and the truth-telling of creative nonfiction…
• What they’re not: fragments. Micro-memoirs aren’t slivers of a bigger creation. They’re designed to stand alone…
• Forget about the big memories, like meeting your beloved or witnessing a tragedy.
• Consider memories that you retain without understanding why.
