I don't recommend deliberately doing high status behaviors to raise one's status. I tried doing this most of my waking hours once, but it was psychologically unsustainable and eventually resulted in a minor breakdown.
Work on your inner game first. Maybe experiment with owning your low status behaviors. E.g. if you notice yourself walking in an uncomfortable way, deliberately accentuate it because you just don't care.
Well, don't do it to a stupid extent, no. But I find this list an excellent summary of useful skills to learn to project. Of course, I'm an arrogant so-and-so with a self-opinion well above observable results ...
I can't remember how I found this, just that I was amazed at how rational and near-mode it is on a topic where most of the information one usually encounters is hopelessly far.
