Flow as you presented in here seems to be the same "flow" that has led enterprising men and women of history into extraordinary works of art, poetry, music , literature, etc. The greater significance of your presentation, to me, is you are reminding a greater number of us humans that we are actively evolving and have yet to arrived wherever we are going or becoming. This idea of flow is of immense importance to every human alive today but yet remains vacuous and illusive. How can we make it a practical knowledge or self-help tool available to all. How can we make it so?
