Can you truly “reprogram” your instincts around money and status, or do your roots always show?

A lot of wealth advice talks about “leveling up your mindset” or “developing an abundance mentality.”

But I’ve been reading about this older sociological concept of habitus; basically, the deep, gut-level instincts you absorb growing up about what feels normal, comfortable, or “like you.”

The claim is: if you grew up middle class or poor, some of those instincts don’t fully go away even after you get rich. You might learn to act differently, but under stress you revert. Or you feel like an imposter at certain tables. Or you hesitate in ways that old-money people never do.

So my question for those of you who’ve moved up significantly (not just earned more, but changed social worlds):

* Did your deep instincts actually change over time? Or did you just get better at managing them?
* Have you noticed differences between yourself and people who were raised wealthy; in how you spend, invest, take risks, or handle social situations?
* Is “fake it till you make it” real, or does the old self always resurface?

Not necessarily asking for self-help advice. Just curious about real, lived experiences.

Tl;dr Does the class you grew up in leave a permanent mark, or can you truly shed it?
