Ep 84 1Cor 9 19 23 All things to all men method of evangelism

I've heard some wild interpretations of this passage over the years, but how does one become all things to all people? There's a lot of diversity out there, so how does one reach and identify with everyone?
It's not that complicated as it turns out, and one does not have to "get drunk to share the gospel with heavy drinkers," as some people I knew used to always say.
Peace to us all in these times of confusion.
