I used to be a total hoarder. Kept EVERYTHING (well, not like rotting food or those weird gross things some people hoard). I even kept all my homework and papers and such from elementary school on until I graduated high school and finally looked through them, just kept the stuff that really meant things to me (poems and essays) and the rest got recycled!
Now I just look like a pack rat because I don't have enough storage and I also hate to clean up!
