* Length varies: Memoirs can be short (50,000 words) or long (100,000+ words). It depends on the scope and depth of the story.
* Focus on quality: The most important thing is a compelling narrative, well-developed characters, and an engaging voice.
* Publishers have guidelines: Each publisher has its own word count preferences, which you can find on their submission guidelines.
Here's a rough guide:
* Short memoir: 50,000 - 75,000 words
