I chose to remove the old unless keys out of one of my draws as my first item. (I know I could have counted each key as single items but I thought it woud be better just getting rid of them all in one go).
Nice one! The day count thing is only a minimum, I've stalled before trying to save stuff up for later in the challenge, all in one go is a much better approach.
I dropped off a bag of pyjama trousers/shorts at a clothing donation bin this morning, that can be my "one".
Find a friend, family member, or coworker who’s willing to minimize their stuff with you next month. Each person gets rid of one thing on the first day of the month. Two things on the second. Three things on the third. So forth and so on.
