Stop Playing Defense, was really enlightening. My biggest takeaway was from Depak Chopra's 7 Spiritual Laws of Success:
The Law of Least Effort
If you observe people around you, you’ll see that they spend ninety-nine percent of their time defending their points of view. If you just relinquish the need to defend your point of view, you will in that relinquishment, gain access to enormous amounts of energy that have been previously wasted.
When you become defensive, blame others, and do not accept and surrender to the moment, your life meets resistance. Any time you encounter resistance, recognize that if you force the situation, the resistance will only increase. You don’t want to stand rigid like a tall oak that cracks and collapses in the storm. Instead, you want to be flexible, like a reed that bends with the storm and survives.
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’.’
If you embrace the present and become one with it, and merge with it, you will experience a fire, a glow, a sparkle of ecstasy throbbing in every living sentient being. As you begin to experience this exultation of spirit in everything that is alive, as you become intimate with it, joy will be born within you, and you will drop the terrible burdens and encumbrances of defensiveness, resentment, and hurtfulness. Only then will you become lighthearted, carefree, joyous, and free.
