Johann Hari has a book out called Stolen Focus in which he discusses the main reasons for our lack of attention. You can imagine social media, due to the current predatory design, is the biggest culprit along with a disconnect from nature, disrupted sleep and toxic environments.
Johann Hari has recently been on both the Rich Roll and Guy Raz- How I Built This podcasts promoting his book Stolen Focus. Check out both podcast links below. Johann pictured with Rich below.
