I've just started playing piano again. I'm no better than I was in high school, which is not much better than I was in Junior High, and I'm not trying to play anything I didn't know then.
But it is so soothing to the spirit to be playing music again. I'd forgotten what it was like.
You could hire the world's best pianist to play for you whenever you wished, and it wouldn't give you what mediocre playing of your own produces--an ability to be inside the music.
Children, everyone, take up an instrument. It's really worth it.
