Guilty

Do you ever feel guilty for the amount of stuff you have?  Stuff...that's all it is.  I was moving into my dorm room for the third time (weird how I'm halfway finished with school) and I realized how much stuff I have.  It's ridiculous!  Yet, I find myself buying more and more.  Why do we do this?  Why do we tell ourselves it's okay to have more?  Where do we draw the line?  These are the questions I ask myself tonight.  What are your thoughts?
