In our culture, the answer is often to look within —to soul-search.
This is also a product of individualism, not that there is anything inherently wrong with it.
There are alternatives. The most obvious is to build one’s own identity. There is also a path to kill it.
When we identify with something bigger than ourselves, the self is no longer important.
This is also rather extreme. But perhaps the middle path is a switch of some sort, a duality.
