At least it is for me.
I'm addicted ot learning things, to history, to stitching, to far too many TV shows to mention, to books (I'm doomed in the next quake), to scifi (don't sue me if you don't like it-- just go grumble to yourself in a corner somewhere). These addictions are concurrently horrible and wonderful, detestable and beneficial. My mom used to say "it could be worse" when I brought home more books or the like. I'd smile and say "yeah it could be alcohol." Oh dear, did I mention my penchant for single malt?
Might you be a bit addicted yourself?
