Merlin Mann summarizes Mike Monteiro's presentation on revaluing time and attention in the workplace. Mike created products to encourage people to think critically about how they spend their own and others' time. Merlin outlines five patterns for better managing finite time and attention: identifying sources of distraction, controlling access to your time, minimizing notifications, working in short bursts, and renegotiating commitments. The goal is to defend your attention and focus it on high-value work.
