I have a bad habit of forgetting things at home when I leave in the morning. I developed a habit: “Wallet, keys, badge, smokes, phone” I pat the pocket each item should be in as I say it out loud.
Unfortunately, I now do this on auto-pilot. I pat the pocket, say the word, leave the house... and realize I don’t have my badge on me when I arrive at work.
I’m thinking about installing a card reader that locks me in the house if I don’t have my badge :)
