If by "zone" you mean "flow," then yes; here's a relevant quote from Deep Work: > The connection between deep work and flow should be clear: Deep work is an activity well suited to generate a flow state (the phrases used by Csikszentmihalyi to describe what generates flow include notions of stretching your mind to its limits, concentrating, and losing yourself in an activity—all of which also describe deep work). And as we just learned, flow generates happiness. Combining these two ideas we get a powerful argument from psychology in favor of depth. Decades of research stemming from Csikszentmihalyi’s original ESM experiments validate that the act of going deep orders the consciousness in a way that makes life worthwhile." Newport, Cal.
