Learning to accept oneself and one's situation is a huge step. Until I got older it never occurred to that a whole lot of other people never do.
Unscientifically, I have long observed that sort of acceptance seems to be more prevalent in those who dabbled in powerful psychedelics. There is some research coming out that suggests that may be true.

This reminds me of the Stoics. I know very, very little about their philosophy, but I know they accepted and even embraced what we would call, "imperfecion" in the natural world, including in people.
