I would say I struggle with cables and USB chargers and such. Like after years of being involved with tech I have multiple VGA and DVI cables that I hardly ever use unless I am messing with some weird SBC.

Sometimes I go through and throw a lot of stuff out. We have a reuse center in town where you can get that sort of cable for $2 so it is not like you have to pay Best Buy prices

Organizing can help. When you put all your VGA cables in place you realize you probably don't need 15 but the 4 best ones are fine (which you also won't use but hey progress). I'm still hoarding IDE cables but at least not a excessive ammount.
