The body remembers repetition more clearly than intention.

What you intend is not recorded anywhere physical. What you actually do, over and over, is. The body responds to frequency, not to plans, and a genuine intention held for years while nothing changes produces exactly the same result as no intention at all.

Instead of resolving to do something significant, do a very small version of it consistently. Ten minutes, most days. Repetition is the only language available here, and small is what makes repetition possible.
