Used to have a ton of bags back when I was working in the office. Backpack with rain cover if there's a typhoon/heavy rain, crossbody messenger bag for my daily use, another backpack that has tethered zippers in case I'm bringing something that needs to be super secured, tiny sling bag enough for just my wallet and phone during Fridays because there's free lunch, and backpack during gym days (when I was still a regular). Also have some rare bags for specialized trips like hiking (the massive Deuter one lol) and a travel backpack when going overnight/2-3 day outings.

Now I only have two bags: a small crossbody and a slightly larger sling for carrying the Steam Deck when on a doctor's appointment.
