Guitar practice

I'm home tonight. Lee's working with his dad and my friends are busy do other stuff. So it's just me and my guitar. I made an interesting discovery. When I first got my guitar, I was practicing almost every day but not getting far. I did make improvements from when I first started, but I seemed to have stopped getting any better. At times it seemed that I was getting worse >.< Well, this weekend, because of the SAT and stuff, I didn't really get much time to practice. When I finally did find the time, I found that I could play better than before I took a break. O.O It looks like the same principle holds for guitar playing as it does for running: take a break.
