The vice of deficit of Resilience is called Frailty, where one is "weak, due to a lack of elasticity, or rigidness", where such a person may seem like "a party pooper" who throws "a wet blanket on everything we dream of and try for." This becomes an incredible spiritual burden on the other partner, in terms of ineffectiveness that turns into chronic "losing."
Its opposite, the vice of excess Resilience, is Capriciousness.
Resilience has bearing on our performance in phase three - intellectual attraction - step eight, where we seek to amplify the best virtues toward our goals. It is what causes us to see our mate as "never say die" in our lives, and us to feel that we will have failures to keep trying to succeed, but that doesn't mean we will fail to win our goals.
