You can’t see your hair grow by staring at it. Check back in a month and act surprised.

Watching does not speed anything up, and at close range it cannot even detect the movement. Your resolution is worse than the rate of change, so continuous attention returns a flat line, and the flat line gets read as failure. About the only thing frequent checking reliably produces is discouragement.

Put the measurement on a long interval and get on with the work in between. Fill the gap with doing rather than watching. When you finally look, the change will seem to have arrived out of nowhere, which is exactly what accumulation looks like.
