At the Academy of Achievement’s 1992 Summit in Las Vegas, Michael Crichton gave a brief talk on goals and intentions. The talk, length [11:10], is available as a free download through iTunes.
Crichton illustrated the roles of the conscious and unconscious minds by comparing them to a small mouse on top of an enormous elephant. The mouse represents the conscious mind; the elephant – the unconscious mind. He said, “And if you want to knock down walls, the notion of which animal, which mind you want to enlist, is I think, very clear.”
