Completely desist from defending your point of view. When you have no point to defend, you do not allow the birth of an argument. If you do this consistently - if you stop fighting and resisting - you will fully experience the present, which is a gift. Someone once told me, "The past is history, the future is a mystery, and this moment is a gift. That is why this moment is called 'the present'."
Deepak ChopraThroughout your day, when you notice that your thoughts have drifted away, come back to where you are. You'll instantly see why you drifted away, whether because you were bored, anxious, dwelling on the past, or anticipating the future.
