In his book “Your Brain at Work,” David Rock depicts the story of two people over one day at the office, and what’s happening in their brains that makes it so hard to focus and be productive. Not only does he explain why things go wrong, but how you can train your brain to improve thinking and performance at work. Based on interviews with 30 neuroscientists, he’s developed strategies to help you  maximize your mental energy by understanding your brain’s limits, overcome distractions, improve your focus through understanding the nature of attention, reduce stress levels with brain-based techniques and improve how you collaborate by understanding the social needs of the brain.
