I don’t know if it’s a legacy, but I always wanted to leave stacks of notebooks behind when I’m gone.
Like Daniel Jackson from Stargate, stacks of notes and information. Notebooks that are a mix of journal and research. Filled with weird drawings and esoteric knowledge.
It’s more likely I’ll leave half completed calendars, and books with 10 pages of chicken scratchings. My children will burn it all and be glad they don’t have to read the mundane ramblings of th parent.
I did once read, that historians loved mundane journals, they give explanations to what daily life would have been. To people studying the past those boring details are golden, explanations of what is obvious now, but fallen out of common knowledge cannot be found anywhere other than these journals.
So my legacy might be mundane details in too many scrappy note pages, but when I die I’ll rest hopeful that there are surprises in the pages, but content that someone will find details helpful in the future.
