Just get your first draft on paper (computer screen). Write and keep writing without editing or rewriting. That way your creative juices will flow without being stopped by details that can be later addressed in rewrites. You're over-thinking all the details and that won't necessarily make for a better first draft, probably the opposite. You can figure out chapters, sections, characters etc in subsequent drafts.
I really have no vision for how I want to arrange my memoir. I imagined going as chronologically as possible, but of course it also makes sense to organize it based on specific relationships, schools, jobs, physical environments, etc. and these of course exist over time. a mixture of both is probably best. what do you all think?
my personality is a bit scattered, so I know inevitably there will be a lot of tangents and spontaneity in my story telling, so I want to be disciplined and not indulge too often in flashing back and flashing forward or mixing up subjects because I'd like for the reader to experience things in a real progression, and not immediately "give away" what I learned about an experience that radically changed the meaning of it, 6 years later. sort of inject an element of suspense, which perhaps is tricky to execute in a nonfiction genre.
I do think my memoir will be long because it is about my entire life. And I have major, disparate themes and events throughout my story. Domestic abuse from childhood, "social political issues" from school years, identity issues throughout, medical health issues toward the later years, etc. I feel like all of them individually could suffice for a short memoir, so together they will inevitably yield something on the longer end of the spectrum. But I will probably pretty easily get it down to 125k.
200k is a bit of a fib. It's a VERY VERY rough draft. A lot of it is unusable at this point.
Regarding the organization. I basically start out with a lot of fluffy, but interesting, childhood memories. I organize them according to the people or group of people they pertain to. But the structure is very "potpourri"-like. A lot of the actual action is a collection of sound bites in a way. The longest scenes are a couple to a few paragraphs. With these chapters, my goal is simply to introduce them to these important people in my life, and any action is simply to demonstrate a quirk about their personalities.
Later on, when I get into some of the more serious events, I do develop them more in depth over an extended time period. But I think part of that is just because they're more recent and more fresh in my mind. In these chapters, I am actually trying to explain exactly "what happened" during these events.
I guess it feels like the first half of my book will be like a scrapbook of memories, and the second half will be like a season of the TV show "24" with like a very developed more "play by play" approach. Just describing it right now, it actually sounds like it could be enjoyable for the reader having that mixture. But I guess I have a permanent instinct that I must be doing this wrong.
No offense, but you'll have to cut out enough to get your memoir under the 120k mark. 200k is way too much to ask a beta reader or an agent to read, especially when you're new. I understand it's a guesstimate and the word count may change, but really work on tightening.
If a scene doesn't really add to the plot/theme, get rid of it. Don't over explain and treat it like a work of fiction. I love reading memoirs. However, the ones I've read have always kept on track, had good pacing and didn't overdo it.
To cut down the word count, try and following.
Use conjunctions (that is = that's) etc.
Remove all forms of passive voice
Remove -ly words (lovely, gently, quietly)
Use a combination of short punchy sentences and longer ones for description.
Use he said and she said. Once the scene opens up, you don't need many dialogue tags at all.
As far as sections are concerned, it really does depend on what the memoir's about. I wrote mine in chronological order and usually broke up my chapters based off of location/time of day.
