You have to master not only the art of listening to your head, you must also master listening to your heart and listening to your gut.

Fiorina frames good judgment as a practiced, multi-channel discipline rather than a purely rational calculation. “Head” stands for analysis and evidence; “heart” for values, empathy, and moral intuition; and “gut” for experience-based instinct—pattern recognition that often operates below conscious reasoning. The insistence that one must “master” all three suggests that each can mislead when used alone: intellect can rationalize, emotion can overwhelm, and instinct can be biased. The quote advocates integrating these faculties, especially in leadership and high-stakes decisions, where data, ethics, and lived experience must be balanced to act decisively and responsibly.
