 Engagement is what flow is defined by—high, high levels of engagement. People experience flow in many kinds of work, from looking at the tiniest cells to exploring the largest scales of the universe. One of the famous cell biologists described flow looking through a microscope; astronomers describe it looking through telescopes. Similar flow states are described by musicians, painters, computer programmers, tile setters, writers, scientists, public speakers, surgeons, and Olympic athletes. People experience it playing chess, writing poetry, rock climbing, and disco dancing. Almost without exception, the flow state is when one does his or her best work.
