As far as pictures go, I've learned to be ruthless with the delete button and only keep photos that I really care about. Mostly, those are the ones with people in them, that record a meaningful moment in history, or with actually interesting subjects. Photography is somewhat of a hobby for me, so I still take a lot of photos, but I'm quick to delete them. This has the side effect that I can store my entire photo collection (10 years/60 GB) on my phone's SD card where they are easily accessible. This has been valuable, because I refer back to photos I've taken years ago surprisingly often.
