Building routine builds habits and tools that will manage energy and hence performance. Routine include breaks away from repetitive activities.  Breaks can take various forms, both passive and active. Passive activities have a low energy payoff. Things like watching television, eating, or social media crawling can be energy vampires that add to the problem. Active activities like physical exercise, social interaction, going outside, or group activities like yoga or sports can be energy sources and perfect breaks from work.
