And most people lived outside civilization entirely. They had very diverse lifestyles, but we can make some generalizations. Even when they didnt leave diaries for us to read, we can infer that they had much less specialization, both from economic principles and from archaeological evidence.
It's certainly true that people in civilizations are, and have always been, focused on martial duty, and everyone everywhere is concerned with religious worship, though they may call it something else for social reasons. But people have always been strongly interested in individual happiness, even in civilizations. The Buddha founded one of the most important religions 2500 years ago on the basis of individual happiness, to the point that after he died, one of the most contentious issues among his followers was whether holy people had any duty to help other people achieve happiness as well, the origin of the Mahayana bodhisattva vows. Epicurus's philosophy and Marcus Aurelius's writings are also centered on the pursuit of individual happiness, as is much of Plato and of course the Mohists. Even religions and philosophies that preached lifelong duty and sacrifice above all else, like Christianity and Islam, offer it as a path to individual happiness in the afterlife.
Well no, civilizations like the Maori are the exception, not the norm. Rigid class roles and specialization have featured prominently in essentially every Eurasian civilization from Egypt to Han China, which held the bulk of humanity and uts developments. Nor did questions of individual happiness matter, what concerned people at the times were questions of martial duty or religious worship.
