Find a second life for your single sock.
I live in a house with boys – a result of which is finding single socks in most every corner of every room – for some reason.
Anyway, I keep a stash of single socks in my laundry room and when I’m quite convinced they are destined to be single forever, I repurpose them as household rags (way better quality than a J-cloth for example) or fabric softener sheets (just a few drops of liquid fabric softener and a sock will replace expensive dryer sheets).
It’s not a big thing – but little things matter and every bit counts. That’s the whole point behind defying your debt.
