I mainly work the night shift, and when I am heading out I would be so tired I might forget something. Before I would head to work I would print up a list of what I needed to take with me, and when I was about to leave I would have a friend or relative read the check list and ensure I had everything I needed. This was not a day to day routine, just when I was going on a trip or something. Also, I would always lose my watch, I never could keep track of one. Then one day the strap on the watch I had broke and I slipped it into my wallet. The watch has stopped working, but I still have it. I know, I have to get a new watch, but it is nice to know I won`t lose the next one.
