Regardless of how you feel inside, always try to look like a winner. Even if you are behind, a sustained look of control and confidence can give you a mental edge that results in victory.
Just fully being skillful involves total lack of inhibition. We are not afraid to be. We are not afraid to live. We must accept ourselves as being warriors. If we acknowledge ourselves as warriors, then there is a way in, because a warrior dares to be, like a tiger in the jungle.
What the warrior renounces is anything in his experience that is a barrier between himself and others. In other words, renunciation is making yourself more available, more gentle and open to others.
