How good are you at paying attention? Test yourself with this experiment (link: https://www.youtube.com/watch?v=vJG698U2Mvo), one of the most famous psychology experiments. Christopher Chabris, PhD is one of the originators of this experiment; he is currently Professor and Co-director of the Behavior and Decision Sciences Program at Geisinger Health System. His book with Daniel Simons, The Invisible Gorilla (link: http://www.theinvisiblegorilla.com/) is a bestseller that goes into much greater depth on the everyday illusions of attention, memory, confidence, knowledge, cause, and potential; as well as the myth of intuition.
