Collecting vs. Hoarding

Many people would say that if you collect enough things it becomes hoarding.  But I disagree.  No matter how many things you collect it's still a collection if they are all in the same specific category.  A collection is an assembly of items such as works of art, pieces of writing, or natural objects, especially one systematically ordered.  Hoarding is when you excessively gather things creating your car and/or house to be cramped to the extent of not being able to walk.  Hoarding also tends to be for people that have a mental problem whereas a collection is for people with a creative eye (mostly artists).
