Life off Earth is in two important respects not at all unworldly: you can choose to focus on the surprises and pleasures, or the frustrations. And you can choose to appreciate the smallest scraps of experience, the everyday moments, or to value only the grandest, most stirring ones.
It's never either-or, never enjoyment versus advancement, so long as you conceive of advancement in terms of learning rather than climbing to the next rung of the professional ladder. You are getting ahead if you learn, even if you wind up staying on the same rung.
