One of the inarguable facts of life is that if you throw away a particular cable you will, within minutes, have a need for exactly that type of connection. We're doing some industrial strength tidying up at the moment, and I've been sorting wires into bags. A number of categories, mains cables, power supplies, network cables, video cables and USB cables. It's actually been quite therapeutic. It's nice to have imposed some order on what was a whole bunch of tangled chaos.
