For me, a big part of staying positive and upbeat at home has been researching where we want to visit next - when it's safe. It's also a good time to take stock of your rewards programs and points so that when the time comes you have a plan to maximize their value.

Also, a good way to "explore" right now - travel through your bucket list destinations with books! I loved this list: https://bucketlisters.com/blog/240-the-best-books-to-cure-wanderlust (my favorite: take a trip to Paris with All the Light We Cannot See)
