My father was a great story teller
. I regret I never recorded audio of any of his stories.
My father sang a few songs in his final months. Those made it to cassette, and I digitized those. Priceless.
I would record yourself doing something you love. Take a walk, and record your thoughts on it. Go for your favorite drive and narrate why you like it so much. Go to the library and give a guided tour. Sniff a rose, and then talk roses.
If you have a lot of "core thoughts", record those.
If you have a great laugh, get that recorded.
And through all those recordings, intersperse your core values, your love...for your daughter, life, your work, space travel or organic zucchini.
I've logged a bit of face time with my replacements. I always emphasize that I would want them to be happy, not sad, when they think of me.
