Braces move teeth a millimeter at a time, and one day the smile is just different. Small shifts count.

Change below the threshold of noticing is still change. Nothing at that scale registers day to day, which is why a process can feel like nothing until the result is suddenly obvious, and the obviousness arrives all at once even though the work did not. Accumulation is invisible by nature.

Set the size of your effort by what you can repeat rather than by what you can feel. Keep a simple record so you have evidence on the days your sense of progress fails you. The difference will look like it happened overnight.
