First, one can look to the mid-Atlantic Quakers, whose own book of daily guidance is titled "Faith & Practice", which stresses the distinction between how one might behave in the world and what one believes about spiritual and religious matters. For (that branch of the) Quakers, you can live a "good life" without necessarily subscribing to any of their spiritual/religious beliefs.
Secondly, most people's idea of their good life is woefully lacking in self-reflection and self-knowledge. What really makes people happy? Civilizations and cultures across time and space all stress that what really makes people happy rarely involves material well being (although obviously a certain level is required to avoid that being the dominant shaper of the experience of life). Yes, we can admit that various gadgets and access to services brings us some level of joy in life, but that doesn't really negate the fundamental truth that what makes us happy tends to be purpose, not products, tends to be who we have in life, not what we have.
