As creators of Google Ventures' renowned 'design sprint', Jake and John have helped hundreds of teams solve important problems by changing how they work. Building on the success of these sprints and their experience designing ubiquitous tech products like Gmail and YouTube, they spent years experimenting with their own personal habits and routines, looking for ways to help individuals optimize their energy, focus, and time. Now they've packaged the most effective tactics into a four-step daily framework that anyone can use to systematically design their days.
