Why not just type an essay about your life and put it out there? You can, of course, but memoir readers have expectations, just as science fiction or romance fans do.
Your piece has to convey a story, or perhaps a series of stories tied together and concluded in some way. This usually doesn’t happen without a lot of work.
WRITING FOR YOURSELF AND FRIENDS
When my nieces and nephews were younger, I wrote a series of humorous essays from an aunt’s perspective. Since I value relationships with them as adults, I would never consider publishing the essays – not even showing them to someone outside the family. But they were rewarding and fun to write.
