Absolutely. They're professional liars. Many people are professional liars of course, but with acting it's inarguable, that's literally their entire job description and sole responsibility.
That aside, there's nothing healthy about want unreciprocated attention/affection from anyone, let alone from millions, let alone actually getting it.
That aside, the demands of modern life are so specialized that we no longer champion well-rounded individuals; instead, we value the people who excel in a single area to a hyperbolic degree. The thing about specialized excellence, though, is that it necessitates sacrifice in all other areas -- think about how many stories romanticize the act of sacrificing everything in pursuit of a single ideal, or savants or visionaries who were otherwise pieces of shit. Hell, Oppenheimer and Ferrari both got movies last year. Excellence in a given area comes from time and effort invested in that area, which necessarily means that time and effort isn't invested in other areas, which precludes you from being a good person, or at the very least from being as good a person as you could be.
And all in the pursuit of a skill that arguably doesn't actually benefit society. I'm hesitant to point this finger at the arts, compared to, say, grown men playing children's games, but none of these people deserve millions of dollars.
It's investing yourself in the act of lying at the expense of the rest of your life in pursuit of unreciprocated attention from strangers and undeserved financial reward. There's nothing healthy about it.
The diffusion the ego for long periods of time is never healthy but to say we don't act multiple times a day would be a lie.
Speak for yourself.
