I recently did something similar, and went from 40 to 30 while bringing a fresher feel to the new number.
Perhaps that was a prelude without me knowing it, because now I feel ready to embark on a next phase: to go from 30 to maybe half that number and without adding in anything new. Before I would have felt that this meant cutting in to the bone. Now I just think it's something I want to do to lighten a load.
