Habit is formed out of memory... We often shape our present situation according to those habitual memories. Instead of starting fresh, we go back to what we've done in the past... easier for us than fighting our way through foreign territory.
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.
