A useful reset starts with fewer decisions, not more pressure. Pick one clear goal, choose meals you can repeat, and add one small behavior that is easy to do even on a busy day.
The point is not perfection. The point is creating a routine that survives normal life: imperfect sleep, work, family, stress, and social plans.
Start with water, a predictable first meal, and a short walk. Once those feel normal, add the next habit.
