Screen legend Cary Grant was wildly regarded as the most charming actor of his generation, and it wasn’t just about his looks. He was once asked what his “secret” was; what was it that made him so charming? He simply replied… “I find people charming.”
Engagement is an interesting thing. By taking the focus off yourself and putting your attention on the character in the scene, you immediately engage and everyone says “wow what great chemistry they have.” As in acting so in life.
If you want to be interesting, be interested in others; if you want to be loved…love.
