If you are someone who constantly misplaces their keys … this challenge is for you!
Where are all your keys? Go and get them. Next, check what keys you still need. We often have keys that we actually have no idea what they are for. Only keep those you actually still need. The others can go. If you worry throwing them out because you might need it in the future, think about this (sorry if I’m a bit provocative here): you don’t know what the key is for, right? What makes you think you’ll know in the future? How big is the chance that you’ll need it one day? Exactly, probably almost zero.
To finish this challenge, label the keepers so you won’t run into the same problem again in the future and put the keys in their home.
