My body, mind, and spirit feel stronger every day.

Nobody has ever felt themselves get stronger on a Tuesday. The change is too small to register against the noise of an ordinary day.

Ask a pianist when the difficult bar became easy and they cannot tell you. There was no morning it happened. There was a stretch of weeks where it was hard, then a run-through in which they noticed they had stopped bracing for it.

Your own version is running now, underneath the tiredness, unavailable to inspection. The evidence turns up late — a hill, a conversation, a week that would have flattened you last year.
