I have ADHD so I get rid of most problems by literally tying things to myself. I have a second belt which goers over my pants and have a hip bag attached to it. In that I have the following;

Disposable nitrile gloves (3-4 pairs)

Hand sanitiser

Power bank (10000mAh)

USB C cable

Thumb drives (one with kids shows, one with software, one blank)

USB A to C adapter

Wallet

ID lanyard

Emergency cash (not in wallet because if I lose my wallet I still have my cash)

Tissues

Aspirin, paracetamol, and ibuprofen

Ritalin

Plastic bags for rubbish

Nasal inhaler (for blocked nose, long term issue)

Car and house keys (attached on a clip, not inside)

Then I have my pockets for phones (I have 2), wireless headphones, and anything else for the day.

By keeping my keys attached I cannot get in the car without my belt bag.
