The city park has free grass, free shade and free courts. You pay nothing but attention.

There is a whole layer of the world that costs nothing and gets treated as a last resort. Grass, shade, courts, paths and benches are all open, maintained by people you will never meet, and mostly empty. The only entry fee is deciding to go. Attention is the currency, and most of us keep ours elsewhere.

Use the free thing nearest you this week: sit in the park, take a ball to the courts, walk the path you usually drive past. Stay long enough that it stops feeling like an errand. Notice how much is available the moment you stop treating going outside as something that needs a reason.
