Your capacity tomorrow is affected by what you demand from yourself tonight.

Tomorrow’s capacity is being set tonight, in decisions that feel unrelated. The late finish, the missed meal, the extra hour, the screen at midnight. None of them feel significant and together they determine what you have available for whatever matters in the morning.

Pick one evening habit that reliably damages the next day and change it for two weeks. Watch what happens to your mornings. It is a small experiment with unusually clear results.
