back

I have a dumbass problem where after I've driven away from home I can't remember if I locked the front door or closed the garage door so I turn around and go back home to check. I've managed to fix this by saying out loud, "door locked - check" and "garage door down - check" when I've done it. Now I just need a checklist to remind me to do a checklist.

It might sound dumb to you but your solution is used by Japanese train engineers before leaving at a station and trains in Japan are really efficient and on-schedule.

It's checklists all the way down.
