Since the early pandemic, I've opted to e-mail 100 of my closest friends quarterly some really long form e-mails. It does take me quite a bit of time, maybe about 40 hours of writing and editing.
What is interesting though, is when I see some of those friends after a long absence, they always would cite something I wrote from the newsletter of interest.
I know there is quantity vs quality tradeoffs out there, but its nice to know some thought I wrote still sticks after several months.
