Given how poignantly you expressed my own experience of living with ADHD Primarily Inattentive (what you called ADD above), and as someone on the cusp of becoming a father, I would appreciate this more than I can express.
As an adult with ADD, it was a miraculous new perspective on tracking all the things I used to fail to do. I so, so wish I'd had it when I was dealing with small children.
I’m constantly playing the “no ones died yet on my watch” card.
It somehow doesn’t make her feel any better.
I can't count the number of times while talking to my psychologist, in the middle of a breakdown thinking "If only there were a system that I could offload all of the dumb things I can't remember to do..."
...and then laughing my way out of the room because my wife told me weeks earlier that she wishes I were using my journal. She notices that I'm happier when I use it, she is much happier because she doesn't have to ask me to do something 4 times...
Using OrgMode for keeping my work-life in order has been a life-changer. But perhaps a bullet journal is more suited for keeping personal, and family life. I've never looked into them properly, but will definitely do so today.
