Like doctor's appointments, and such.
I'm not always real good, at keeping appointments. I used to say it was difficult, cuz I never know what mood I'm gonna be in----but, now I realize it's not my MOOD, per se, but what I'm doing, and if I'm deeply engrossed in my "interest of the moment", then I don't wanna be interrupted.
OTOH, it's good for me to set a time for something, otherwise it might never get done.
