Stop worrying about a well collated archive and just dump everything in a suitable storage medium. I've got years of random side projects and pretty much every photo I've taken going back many years. It's a complete mess, with various duplications, it's just not that big (few hundred GB maybe? I'm away from home so can't open up my NAS and look) so not worth my time to optimize it.
On the flip side it's fun to randomly browse through and take a trip down memory lane. When there's a particular thing I definitely want can be more of a pain to find than if I had any decent organization but that comes up rarely enough that I don't really care.
