I have a problem...my landlady says that I need to find a way to get rid of things! I hate the word "rid" and getting rid of things!

I'm kind of a pack-rat, but...is renting a storage garage a good idea? Because all I know is that the day my dad dies...I'll have more stuff that I'll be receiving.

The easiest thing I can get rid of is clothes since most of time I will wear them as work clothes and they can get demoted as rags or I may not fit into something. Should I rent a storage garage?
