What is the most valuable thing I own?

2012:
There isn't any monetary 'thing' I own that is valuable. I have my wedding jewelry. But that's about it. I can walk out of this home and not give a second thought. This iMac and then my dSLR camera are the only things that comes to my mind with any value to it. Of course, over the years, my hard drive is filled with graphic files(digi scrapping) that probably cost more than the computer. My photos on the hard drive are invaluable!

2013:
Still same as above! Not much has changed over the year! Photos and my Layouts are the only valuable things I own.

2014:
Memories with family.

2018:
Don't own anything tangible that is valuable!
