Overthinking is creativity stuck in a loop. Make something, anything, to break it.

Thinking about a problem and circling a problem feel almost identical from inside. The circling version keeps producing new considerations and no new material, and it can eat a whole afternoon while feeling productive. The loop runs on nothing entering it. Making something, even badly, puts an object in front of you, and an object gives your brain something real to react to.

When you catch the loop, set a short timer and produce anything inside it. A rough sketch, a voice note, one paragraph. The point is to break the circuit, not to be good within ten minutes.
