Just as the good life is something beyond the pleasant life, the meaningful life is beyond the good life.
The good life consists in deriving happiness by using your signature strengths every day in the main realms of living. The meaningful life adds one more component: using these same strengths to forward knowledge, power, or goodness. A life that does this is pregnant with meaning, and if God comes at the end, such a life is sacred.
The good life is using your signature strengths every day to produce authentic happiness and abundant gratification.
