When you are present, when your attention is fully in the Now, the Presence will flow into you and transform what you do. There will be quality and power in it. You are present when what you are doing is not primarily a means to an end (money, prestige, winning) but fulfilling in itself, when there is joy and aliveness in what you do. And, of course, you cannot be present unless you become friendly with the present moment. That is the basis for effective action, uncontaminated by negativity.
