We might need a new slogan for this quarantine: "Stay sane and use your brain!" So, on with it:
Start your memoir:
Yesterday we suggested a journal. Another approach: your life story, or some part(s) of it. If you don't think you have anything important to say, start with what's changed since you were a kid. After all, we've come through huge international events, from the Cold War to JFK to the space program, to say nothing of going from telephone party lines to videoconferencing. Maybe a little writing each day, so it doesn't seem overwhelming?
Keep informed about Covid-19:
The New York Times has a free newsletter:

When was the last time you sang out loud? It's impossible to be depressed when you're singing. Rusty vocal chords? Nobody cares. Take inspiration from the Italians:

Have a virtual party:
My kids and I had a cocktail party. We each created a cocktail or non-alcoholic party drink from ingredients on hand and gave it a name. At 5:30 we posted photos and chatted via text.
Photo: my invention, "Washington's Monument."
There are endless possibilities: a cookie party, appetizer party, smoothie party.
