Lasting change comes from small, repeatable actions — not overhauls that fade in two weeks. Pick one habit (water with meals, a daily walk) and stack from there. Environment design beats willpower: keep healthy options visible and less-healthy ones out of sight. Track the behavior, not just the outcome. Showing up daily matters more than perfect intensity.
Key facts:
It varies; consistency over weeks matters more than a fixed number.
One miss is normal — resume the next day; don’t scrap the whole effort.
