Anything that I know I'll have to do over and over again, I work up a system - a series of steps that can't vary, or it'll throw me off completely.
I've been a mess for the last week, both in mourning, and because my dog's death has thrown my "home from work" system into chaos. Coffee doesn't get set up, parrot sometimes has to demand food NOW! because I had to skip getting dog food ready and everything else suffered.
