Caring for your body is one way of respecting plans you still have for your life.

Whatever you still intend to do with your life requires a body capable of doing it. Taking care of yourself is a way of taking those plans seriously, and neglecting it quietly says that you do not expect to get there. There is no need to make it about virtue. It is a straightforward matter of consistency between what you want and what you maintain.

Name one plan you still hold for ten years from now. Ask what it requires physically. Let that shape one habit, starting this week.
