Here is what I have learned.*
keep in touch with those you love
Whoever you love, check up on them - even if all you can manage is phone call.
Interpersonal connections are vital to us as a species. Keep them alive.
LOOK AFTER YOURSELF
When this ends (as the saying goes: this too shall pass) we may find the world just that little harder to be part of at first.
Make sure you are at the best you can be. You owe it to yourself AND to those who are working hard so the world doesn't fall apart right now - they will need support when we crawl out of our bolt-holes.
