Every day when I come home from my night shift I empty my pockets of essentials. Notes and reminders that act as my brain, pens (so many pens), and chapstick because I don't drink enough water. I typically have alcohol pads, folded pieces of tape, sometimes a flush or two, gum wrappers, glasses to keep stuff from spraying in my eyes (yes, its happened). All a reflection of how that night had gone.
I keep a notebook with me all the time that has notes on how to page different teams, phone numbers I don't want to forget, where to find specific supplies, or tricks and memos of how to do different things so I won't forget.
