Hair grows about half an inch a month. Nobody sees it happen, and then one day it touches your shoulders.

Growth happens below the level you can notice, which means the absence of visible change is not the absence of change. A rate too small to see from one day to the next still adds up to something undeniable over a year, and the whole process happened while you were not watching. Perception is a bad instrument for anything that slow.

Stop requiring evidence this week from whatever you are working on. Keep the practice going at a boring, steady rate and schedule one look back in three months. Between now and then, trust the rate rather than the feeling.
