Attention becomes strength when chosen deliberately.

Attention that drifts wherever the day sends it is spent without being chosen, and the results are correspondingly arbitrary. When you decide in advance where it goes, the same capacity becomes something you are aiming rather than something being taken. That deliberateness is what converts it into a strength.

Start your day by naming where your attention will go, before anything asks for it. Defend that choice for at least a few hours. The difference between chosen and captured attention shows up quickly in what you produce.
