In my case, I would say the
quality of my writing has largely improved all the way along...
... unfortunately, the quantity started dropping way off. Way.
I need to find my way back to a happy medium. That said, in the old days my writing was driven by my emotions, often rocked by my latest infatuation or old schoolboy crush. These days, my current reality doesn't really drive my emotions sufficiently to gin up much creativity.
But my fingerpicking has really improved. I've got that, anyhow. For
now.
