"Use tactile feedback to predict outcomes before acting Eagle McMahon and Jeremy Koling describe how elite disc golfers evaluate a disc the moment they pick it up, before ever throwing it. Koling explains, "the second we touch a disc, we know if we're going to end up using it or not," and describes pressing the dome to listen for a specific pop — what they call "the heartbeat of a disc" — as a signal the disc "just wants to keep flying." Training yourself to develop sensory benchmarks in your own domain — whether evaluating materials, food, code quality, or a handshake — lets you make faster, better-calibrated decisions before committing resources.
