Listening.
If you really listen, you acknowledge (to yourself) that you cannot know everything. That there are things that others know better than you do. Listening therefore means automatically recognising and utilising opportunities before others. Recognising risks before they become a danger. Looking at it this way, the ability to listen is absolutely vital. Before the invention of radar, people used enormous ear trumpets with which to monitor air traffic by listening carefully.
