Maintaining a version of yourself that isn't real takes energy. The real version is both easier and more attractive.
When you're real, the people who respond positively are actually compatible with you. Performing attracts people who like the performance.
Real has a texture that performed doesn't. You can't always name it, but you can feel when someone is actually showing up.
The specific, unusual, slightly weird things about you are what make you memorable. Generic is forgettable.
The simplest, most effective thing you can do in any conversation is show up as yourself. Full stop.
