Your free time isn’t empty time. It’s time you get to aim.

Free time gets treated as whatever is left over, so it fills with whatever reaches it first, usually a feed. Having no plan for it is not the same as having nothing you want from it, and the difference between those two is the whole experience of a Saturday. Aimed time can still be lazy. It just got chosen rather than defaulted into.

Pick one thing in advance for your next free afternoon, however small: a skate, a film, a bike ride, two chapters. Decide before the afternoon starts, because deciding inside it rarely happens. Lazy on purpose beats lazy by accident.
