I used to think this way, but now I know better.

My dad passed a few years back, this past year I spent a considerable amount of time helping my mom and sister tame all his junk. So much junk was tossed or donated, very little was kept and even less sold. Not wanting to burden my family with all of my junk I started working on my own hoard this summer. Letting go wasn't easy, but once it was done I felt less burdened by it.

And yes like clockwork a week after tossing it all I needed some random cable. I spent a couple of bucks for one at Walmart of all places, but Amazon and ebay would have had my back if that cable hadn't been there.

If you have a similar junk box, you have my permission to just throw it away. Don't look in it, don't worry about it, just toss it. You do not need to be carrying so much junk. You do not need 20 year old ethernet cables, 30 year old scsi and ide cables, or 40 year old audio cables. You can buy new ones, in new condition today, most of which are reasonably priced and wont produce random errors or noise due to internal faults.

tl;dr- You don't need it, toss it and do it today!
