The myriad little errands and details of family life. They're sometimes harder to remember than the big stuff. Here's how Duane keeps them top of mind:
I doubt I'm the only working parent who can't find his own two feet in the mornings when I'm rushing out the door. Often there's something I'm supposed to do while at work – make a call, pay a bill, mail a letter – and 99% of the time I'll just run out the door without it. Until I start leaving my car keys on the counter, on top of whatever it is I'm supposed to remember. Guaranteed way to not leave the house without it. Of course I may still forget about it after I get to work, but that's a different story :).
We've all got different ways we "tickle" our memories. I've got a bench by the front door that holds all the stuff to go out with me. That works well, but the bench usually looks like a junk heap.
I've also gotten into the habit of writing many things in my calendar twice: once for the actual event, and another time a few days earlier as a reminder. (Electronic calendars let you set reminders automatically.)
I also write down all sorts of stuff I used to just keep in my head: school form deadlines, stuff going on in friends' lives, things I've offhandedly said I would do ("sure, hon, I'll get the oil changed" or "I'll call Tara's mom and schedule a playdate"). It's not a perfect system, and I still find that the fragmented nature of time-after-parenthood distracts me, but I'm getting better. (And I have little excuse — both of my kids are now in school.)
How do you remember the little details?
