Quite true. Making things problems is definitely a good method.

Also, similarly, even if it's not a problem per se - I remember things I need to take with me because they're on my desk right behind my keyboard.

Of course, I almost and do occasionally forget the most basic things. Wheelchair user, I wear gloves and sometimes I forget. I also hate not wearing a hat, and sometimes I forget. heh. It sucks when it's the KEYS I forget though.
