It’s harder to go 99% than it is 100%. When you go 100%, you are in the Flow, the energy is streamlined with high creativity. When you go 110%, you leak energy and struggle.
In positive psychology, flow, also known as the zone, is the mental state of operation in which a person performing an activity is fully immersed in a feeling of energized focus, full involvement, and enjoyment in the process of the activity. In essence, flow is characterized by complete absorption in what one does. Named by Mihály Csíkszentmihályi, the concept has been widely referenced across a variety of fields (and has an especially big recognition in occupational therapy), though the concept has existed for thousands of years under other guises, notably in some Eastern religions. Achieving flow is often colloquially referred to as being in the zone.
Flow shares many characteristics with hyperfocus. However, hyperfocus is not always described in a positive light. Some examples include spending “too much” time playing video games or getting side-tracked and pleasurably absorbed by one aspect of an assignment or task to the detriment of the overall assignment. In some cases, hyperfocus can “capture” a person, perhaps causing them to appear unfocused or to start several projects, but complete few.
Flow is so named because during Csíkszentmihályi’s 1975 interviews several people described their “flow” experiences using the metaphor of a water current carrying them along.
