I've been sorting/stacking scores and books -- well, mostly scores -- per inspiration received from DR Elmore's moving and organizational activities... and I just got rid of well over a cubic foot of music (just have to figure out who to give it to!), and put another half a cubic foot of related paper into the recycling bin.
That doesn't sound like much, does it? Well, there's a lot more to go through. And in psychological/emotional terms, trust me, baby, it's a lot. And it feels good. Every little bit helps.
