What things are items you take with you almost every time you leave the house? What's their purpose? Guys, what's in your wallet/bag/breifcase, ladies, your purse, bag, pockets? I carry a backpack to work, everything goes in it. I have leftovers for lunch most days. A small bag of emergency items: dry socks, space blanket, lighter, matches, paracord, paper, Tylenol, alcohol wipes. For a scenario getting stuck in snow/mud in the country (where I grew up and my mom still lives) overnight. Hunting knife: wrapped in paracord with a ferrorod. Open boxes and self defense (did martial arts for 20 years.) Keychain with LED flashlight: office keys, house, two cars, both divorced parents houses, few membership cards, mailbox, few misc. Power outages, walking the dog in the country at night. Bottle of water. Don't drink them often, more for emergencies. Periodic table / math notecard: I do a lot of math and found it useful to have a list of formulas that's I use a lot. Insurance, credit, membership cards, drivers license, nothing exciting. Fidget cube: I get anxiety and fidget enough that I used to need xanax (yes it was prescribed) but I find keeping my hands busy relaxes me so I haven't needed it in months. Enough cash to be able to get by for a day if for some reason I can't use my credit card. Wife may use it and forget to give it back and I don't want to get stuck. Wallet knife. Multi tool like a cheap Swiss Army knife. I use it a lot at work because of the screwdriver. Paranoid that I'll forget about it and try to get on a plane, but it was cheap so I wouldn't be terribly upset if I had to throw it out. My phone: mostly taking to wife and reading/YouTube on the bus.
