Have you ever had the experience of becoming so immersed in something that you completely lost track of time? Psychologist Mihály Csíkszentmihályi observed this in his work and called it "flow state."  Flow state is described as your peak productivity and happiness happening simultaneously.  Athletes refer to it as "being in the zone," for musicians it's "aesthetic rapture."

Statistically speaking, 85% of people have experienced flow at least once in their life.  But wouldn't it be great instead of surrendering ourselves to random moments of flow, to be able to create a lifestyle of flow that we regularly experience.

The first characteristic for people that regularly experience flow is that they are optimistic.  Keeping a gratitude journal helps mold your mind to think optimistically and is the first step to a greater experience of flow in your own life.
