For the most part, my photos are my most valuable items. I'd be dragging out armloads of photo albums, boxes of prints, and computer hard drives. (I would obviously die in the attempt to rescue all of my memories.)
For the purpose of a journal entry, let's expand the question beyond what you could carry out the door in a crisis. What are your prized possessions? You can:
-Make a list of all your favorite things.
-Tell the details and stories behind them.
-Write about where you'd like them to end up when you don't need them anymore, in other words, bequeath them
-Ask your kids, spouse, parents, etc. the same question and compare your lists
I bought this painting in Barcelona in 2001. It definitely makes the list.
