I think one’s theory of reality is shaped more by subconscious/latent consumption of the same ideas repeated over time, as opposed to any individual thing (eg book, relationship, event) having an outsized impact

Not to say latter category has no effect but just at scale former tends to overpower

I agree, our worldview often evolves gradually from the quiet echo of recurring ideas in our environment. Big events or books might spark change, but it's the consistent hum of subtle interactions and observations that truly molds our understanding of reality over time.
