Nature reminds you that slow change is still change.

We register change when it is fast enough to notice and dismiss it when it is not. But a glacier moves, a shoreline shifts, and a habit practiced badly for a decade has entirely rearranged a life. Slowness affects visibility, not reality.

That cuts both ways and is mostly encouraging. The small good thing you are doing is accumulating even though you cannot feel it. So is the small bad one. Look at the direction rather than the daily increment.
