> the idea of we are going around experiencing things and our life is a product of these experiences we consume and interpersonal politics - that's very california "the personal is the political"

That's a very superficial reduction of the meaning of that phrase. It's worth reading the original 1969 essay with that title:

This quote might help understand the context:

> The bad things that are said about us as women are either myths (women are stupid), tactics women use to struggle individually (women are bitches), or are actually things that we want to carry into the new society and want men to share too (women are sensitive, emotional). Women as oppressed people act out of necessity (act dumb in the presence of men), not out of choice. Women have developed great shuffling techniques for their own survival (look pretty and giggle to get or keep a job or man) which should be used when necessary until such time as the power of unity can take its place. Women are smart not to struggle alone (as are blacks and workers). It is no worse to be in the home than in the rat race of the job world. They are both bad. Women, like blacks, workers, must stop blaming ourselves for our “failures.”

The author was dealing with and responding to very real oppression, and pointing out in part that day-to-day interactions were consequences of, and contributors to, that oppression. That's one sense in which "the personal is political."

The introduction also points out where the overall insight came from:

> However, many on the SCEF [Southern Conference Educational Fund] staff, both men and women, ended up joining the criticism of women getting together in consciousness-raising groups to discuss their own oppression as “[navel]-gazing” and “personal therapy”—and certainly “not political.”

> They could sometimes admit that women were oppressed (but only by “the system”) and said that we should have equal pay for equal work, and some other “rights.” But they belittled us no end for trying to bring our so-called “personal problems” into the public arena—especially “all those body issues” like sex, appearance, and abortion. Our demands that men share the housework and childcare were likewise deemed a personal problem between a woman and her individual man.

In that context, the personal was political in a very concrete, direct sense.
