The worst thing you can do is be physically in a thing — a relationship, an event, but be emotionally out.
This is related to the maxim “don’t worry about things you can’t change.” It’s also: “don’t worry about things you won’t change”. If you’re going to be in the bar, and you won’t change it, then don’t worry about it. Don’t resist it. Find a way to enjoy it. But if you’re unwilling to do that, then leave.
Most of all: don’t stay in the thing, but be emotionally resistant. You’re going to die. That’s no way to live.
