As we get older, we accumulate more things than we need. To make room for the important, it’s good to part with items that go unused and untouched. To help us decide, we should use the fingerprint test.
What items do we touch the most? These items get to stay.
If our fingerprints haven’t touched something, why? Are we not respecting something we value, or it its value, in practice, less than we believed? Add more fingerprints or let go.
