From the book "Attention Management" by Maura Nevel Thomas, published in 2019. The main body of the text introduces the concept of attention management as a modern solution to productivity issues, arguing it's more relevant than traditional time management in our distraction-filled world. The author explains four quadrants of attention management (reactive & distracted, flow, daydreaming, focused & mindful) and offers strategies to control technology, environment, habits, and thoughts to improve focus and overall well-being. Ultimately, the text emphasizes that mastering attention is crucial for living a life of choice rather than constant reaction.
