Optimal Performance: Knowing Who You Are

Have you ever experienced being in flow, fully immersed in a complex activity like writing or reading, dancing, singing, listening, walking, solving a problem, communicating, playing in a sport, doing yoga, running or just sitting. You are an actor, playing your role. There is no director; no script. It's performance time. Everything is just happening. There is a sense of clarity and expansiveness. YOU have vanished. Performance in these moments is as close to perfect as it gets.
How often do you experience such moments? How often could you be experiencing them?
Flow can be cultivated. Imagine being completely immersed without distraction in whatever you do for increasingly longer periods of time. You would experience optimal performance, free of unnecessary stress.
