Today at a Glance:

• When compared to our ancestors, our lives appear to be filled with significantly more attention-grabbing pulls in a variety of directions. Our attention is more divided than ever.

• Attention residue is the idea that there is a cognitive cost to shifting your attention from one task to another. When our attention is shifted, there is a "residue" that remains in the brain and impairs our cognitive performance on the new task.

• To fight back: (1) Work in deep focus blocks, (2) take regular walks or breathers between higher value tasks, and (3) batch processing times for messages. Implement these three strategies and you will immediately see a difference in your work quality and efficiency.
