How do you get into a prosocial mindset?

You know the rare occasions where you’re operating at maximum wit and social flare and there’s no anxiety or self-doubt getting in the way?

Besides from liquid confidence (which I don’t want to rely on) what are some tips that help you enter that zone?

I find that getting enough sleep, meditation etc can help but ultimately I don’t seem to have much control over it – some days are just a lot better than others.
