A common problem in painting is that you can get too fixed in subject, style and process. Experimentation is always good to keep from getting into that rut. Another thing that you can do is switch mediums.
Every few years I take a break from watercolor painting and switch to oil painting. The process of painting in oils is the opposite of painting in watercolor (paint light to dark in watercolor, and paint dark to light in oil painting) which forces me to think about what I am doing.
Now it is time to switch back to watercolor painting and thinking light to dark once again.
Because of the pandemic, I had much more time to paint. These are the oil paintings that I completed over the past three months.
