This article is countersignaling. It also happens to be directionally correct.

As far as I can tell, you jargony phrase means that this is something like the humble part of "humble bragging". I'd disagree, I think the article gives honest good advice, an honest "meta-analysis" of social status and jumping into new things. It's "actionable", something you can do.

I would add that its advice for the sort of person who is normally always thinking about and fairly competent with social status and is held back from new skills by this. I personally was never too worried about social status and have learned massive new things by just being willing to try them but wound-up bitten by my ignoring of status. My advice for my younger me is to be strategic about publicly ignoring status but keep going into private.

Also statements like "she succeeded 'cause she was tough" are meaningless as advice or actionable/verifiable statements. Maybe she succeeded 'cause she had a bunch of strategies like the one she outlines, maybe she succeeded 'cause of good luck, maybe she succeed by family positions, maybe "luck", "toughness" or "mojo" did it.
