There's something to be said for the gratification I get from self-improvement. The longer I do music, the more subtle my evolution as an artist becomes: I sing a little better with each album, my composition becomes a little less childish, my production techniques grow more tasteful, but progress is mostly in small increments. It's not the same as when I first started playing in a band in 1995 - long nights at the bandspace grinding out a challenging passage for forty minutes and suddenly my fingers finding their zone, and that eureka when we get through the section without stumbling. Those breakthroughs are rare now - I'm more likely to experience them while playing the drums or the bass, or looping something.
But I'm getting really pumped on this nude drawing class because I get that feeling two or three times a session. I'm still struggling with proportions and weird angled limbs, but I'm making big strides in muscle tone and utilizing the full spectrum of a black-to-white gradient. And I'm finding the patience to finish the pieces a bit more than before. One of these days I'll have something worth putting my name on.
