Dan Heath is a New York Times best-selling author previously known for his work as one-half of the Heath Brothers. In his first solo book, Upstream: The Quest to Solve Problems Before They Happen, Heath explores the concept of “Upstream Thinking,” and identifies barriers like tunneling, problem blindness, and a lack of ownership. Upstream Thinking could be as simple as purchasing a second power cord, or scheduling time to go on a walk. Whatever the outcome is, upstream thinking helps us avoid problems and save time.
