In this episode, Dr. Killeen shares a simple mental model that can sharpen decision making and reduce overwhelm. Knowledge is rooted in the past, but decisions shape the future, and that gap highlights the power of just in time learning. Instead of trying to master everything at once, he encourages focusing on the information that directly supports the problems you are solving right now. When learning is timely and practical, it sticks. The goal is not to know more. The goal is to decide better.
