QotD: Cards & Letters

What do you do with the cards and letters you receive?  Do you keep them all, just keep the photos, throw them away? 
Inspired by jacolily.

I enjoy keeping the cards and letters I have gotten over the years.  I especially have held on to the ones I got while I was in boot camp.  Those cards and letters made a tough mental game easier to handle.  I would not want to be a person who never receives any letters or cards from the people I love.  I hope my letters and cards are held dear to my family's hearts.  I am sure they will be especially priceless here in the next few months when I deploy to Iraq.
