Meaning in life is arbitrary.
Why ruin the universe with rigidity?
Why do we make the choices we do? After all, we do not have unlimited freedom to do things. We find ourselves constrained by our gender, our race, our economic circumstances, our personalities that were shaped both by genetics and the random processes of life. Furthermore, we find that other people have their own ideas of what we should be doing, and they constrain us still further.
A person born into one culture will have entirely different options that one born into another. They may both lead valuable lives, but they will most certainly differ in many respects. The meaning that they find will come from different palettes. We cannot say that one person’s life is more valuable than another’s.
Of all the people who have lived, have any of them been truly “better” than another? We see in their lives only the exercise of preferences, not differences of inherent meaning.
All meaning in life is arbitrary. It is not tied to god, family, or self unless we define it as such. Nothing in life gives us meaning in and of itself. It is we who assign meaning to objects and relationships. We all try to make the structure of our meaning pretty, but in the end, there is no escape from the feeling that it is all arbitrary.
It might be better not to ruin the universe with our own patterns.
