This ran in 2015, but it’s worth mentioning again.
We all have relatives of whom we neglected to ask questions or otherwise probe for family genealogical information.
If you have relatives who have pictures you’ve not identified, try and identify them now.
If you have relatives who have pictures or other ephemera you’ve not digitized, do that now.
If you have relatives to whom you’ve not talked about the past, do that now.
If you have relatives who would consent to DNA testing, do that now.
That should be enough of a laundry list and probably is actually more than one tip.
