Today, I set a timer for 10 minutes, took in a full sized black trash bag, and figured I'd try to fill as much as I could in that time.
The bag was full way before the timer went off, and I can probably fill most of another one with actual food packaging trash before I even have to start looking at what I pick up.
I need to pick up the pace because we have a houseguest coming in just under two weeks, and that room has to be fit for someone to sleep in.
