I hear you. Same here. One strategy I have long since applied is always carrying a notecard in my breast pocket. Whenever someone tells me to do something or I have an idea of something I need to do, I jot it down, then I periodically look at the card to remind myself of what I have to do. I experimented with using my smartphone for this, but it's too easy to forget about a note in a smartphone, so I always return to the notecard in my breast pocket.
