That's exactly the way I felt with "stuff", little things I collect saying to myself, "I'll need this some day". You know, a few old semi-functioning laptops, cable ends that I'm going to use (I swear!) on my next project, etc, etc.
I had a whole room filled with this crap, until I realized, when was the last time I actually used something from this stuff, whose sole reason for existence was for me to collect, to then someday use.
My answer was years - so I tossed it all a few months ago. You know how many times I've been working on a project and damned myself for throwing all of it out? Zero! Long story (sorry it's a slow day) short - sometimes you just gotta let go...
