Csikszentmihalyi argues that the majority of the time during everyday life we are not completely focused on what we are doing, we are thinking about a conversation we had yesterday, or worried about a test we have next week. But on the rare occasions when we are doing something which we really love, be it skiing, playing poker, listening to music or cooking a meal, we may experience moments where "what we feel, what we wish, and what we think are in harmony," Csikszentmihalyi calls these exceptional moments of complete immersion, flow experiences.
There are two important factors that seem to be required for flow to be experienced, the first is, the balance between ones skill and the challenge involved must be equal and high, too great a challenge and one will get frustrated, not enough challenge and one will get bored, if skill and challenge are balanced but low then one will fell apathetic to the task. Csikszentmihalyi thus suggests that "flow acts a magnet for learning" the more we participate in the activity the more our skill increases and the higher challenge we have to set ourselves next time. The other important factor in flow is that we must have clear goals and receive immediate feedback on our actions, for example the mountaineer getting one step closer to the summit.
Csikszentmihalyi highlights that we all have flow experiance which add to the richness of life. by identifying it's sources and understanding it's benefits we can seek to find more flow experiances and thus further enrich our lives.
