I say the same exact things to others about my experience. I love that it captures a snapshot of my life a truly unique period in US history. It captures my adventures jogging through the center of NYC busy streets during the lockdown, and all sorts of other adventures. I can tell you in reasonable detail every single notable thing about my last holiday trip, or any other place I've been.
I've also become the de-facto historian in my household. When my wife remembers something and wants to know a detail about it, I'm usually able to give at least a general summary of the experience.
In order to get over any resistance, I made a deal with myself that I could put as little or as much in as I want, and that I wouldn't be too personal. I guess you could say it's somewhat of an everyday travelog. It's the first time in my life that I actually carried through with journalling.
I've also been able to pick out trends when I compare the data on my Whoop vs activities and meals on a certain day. I don't always capture my meals, but I do often enough that it provides help when I'm trying to find a trend.
Here's a really strange random trend I discovered: On nights where I eat burrito bowls from Chipotle, I get measurably more deep and REM sleep.
I could go on all day about the ways my journal has been useful. I'll leave it there.
Edit: Just for fun, I send a link to this thread to my wife. She mistook your post as being from me at first. LOL
