You should try changing something small, either more or less of something, a different kind of something, just find a way to spice things up and see if you get better or worse. If you get better keep doing that thing, but if you get worse think about why what you do made you worse and do the opposite of what you just did to see if that makes it better. Finding ways to improve takes a lot of trial and error.

There's 4 stages of learning, unaware incompetence, aware incompetence, unaware competence, and aware competence. When you get good enough to realize HOW you need to improve, you can often feel at a state of stagnation, or like you're getting worse. In reality, you've gotten good enough to be more self critical. Keep going! You ARE getting better!
