collecting vs. hoarding. what's the difference?

I think there is a big difference between collecting and hoarding. If you are collecting something then it should be a collection that are of specific things or a certain type. If not and you just save anything an everything that mean nothing then you may be a hoarder. I think hoarders are people who don't have reasons to save or keep things they do,but they do anyways. As to collectors who have reasons and value to the things they are keeping.
