How do we find the best way to proceed in the world?

Nietzsche seems to have thought that people define “truths” to make life easier and not necessarily because they are actually true. But I think the truths of human nature are derived from biology and are physically easier than the untruths and lies of metaphysics and philosophy, which are tiring---energetic people can be good liars.

How we apply the foundational instincts of biology and how we relate them to human nature and morality determines our culture, our religion, and our success. We need to take our answers more from biology and less from metaphysics and philosophy which grow out of biology.

There also seems to be “courage” involved in finding and telling the truth, not necessarily connected to intelligence. Highly intelligent people can be highly wrong. But courageous people can be wrong too, so it seems to require a combination of courage and intelligence to find and state the truth at any given time.

How do we find the best way to proceed, given our now crowded world of distinct people and states? History has shown us that Imperialism of various kinds does not last and eventually breaks back down into regional states or ethnostates. This seems to suggest that ethnopluralism with distinct regions and small states for distinct people is both the rational and instinctive way to go---but independence would need to be protected by at least a light form of federalism.

We are all more or less infused with the desire to succeed, or the desire for distinction, the idea of actual equality is opposed to common sense and seems to be rather insane. But the natural desire to succeed needs to be based in the sacred, essentially, that is, not on Nietzsche's goalless will to power but in the Spirit-Will-To-Godhood that activates material life, which is then shaped by natural evolution.

If there is a  better way than this to proceed in the world and out into the cosmos I want to know about it.
