Here is an idea to get you thinking about you and your experiences. This is your history and writings of your individual experiences.
I come from a family of list makers. We have the general “to-do” lists, grocery lists, and chore lists. We do break out the spreadsheet apps for larger projects; I have been know to make spreadsheets for Christmas lists, potential car purchases, and trips to Disney World. All of these are meant to be disposable and not meant to be a record of my life.
I do make lists that I intend to keep. I regularly keep a list of books that I have read at the back of my journal. I frequently forget books that I have read, so it is a nice reminder to me of what I have finished reading, I once got 3 chapters into Stargirl before I realized that I had read it previously. It is also a record of how my life has changed as the type and number of books change.
Books read in 2021 so far.
I have been thinking a lot about how my journals can give my posterity a view of what life was like for me and the books that I consume gives not only a glimpse of my life, but a window to my mind at that particular time.
