But now I'm teaching again in a few days. I'm looking forward to the class, Statistical Natural Language Processing, but I'm not looking forward to less guitar and exercise.
I think my latest epiphany is a "re-epiphany": don't strum at an angle. I think I tend to slump over the guitar which leads to sloppy strumming. I just notice the strumming doesn't sound so good, but I don't know why. It's always the bad habits though, the ones we think we work ourselves out of only to find them back again.
