The One Thing: The Surprisingly Simple Truth Behind Extraordinary Results focuses on the concept of focusing on a single task to achieve maximum productivity. It argues that by narrowing your focus to one thing at a time, you can eliminate distractions and achieve better results in less time. The book provides a framework for identifying the most important task in any given situation and managing the 'chaos' that arises in other areas of life when you prioritize so heavily.
There's a book called The One Thing, and he talks about this pretty well. He talks about if you're going to focus on the one thing, then you have to be okay because some some part of your world's going to go into chaos.
