Where do you store your memories?

This is a picture of my memory box.

It's slightly bigger than A4 (printer paper size). I have an A4 folder in there with my goals from every year since 1998 (nerdy, I know, but that's me!), which is when I started setting goals properly.

I have some birthday, Christmas, and anniversary cards, notes from people, etc. in there. Of course I don't keep everything and when the box starts getting too full, I go through it and see what I can let go of.

This works for me because I'm restricting my memories to a container and creating a physical boundary.
