In a survey of 425 psychologists, social workers, psychiatrists, and marriage and family counselors, almost all of them (96%) thought that becoming more “open, genuine, and honest” was an essential requirement for mental health. Let me point out that they didn’t merely think honesty was a good idea. These people, who spend every day working with peoples’ real-life problems, are convinced that honesty isessential for mental health. A requirement.

Of course. Think about it. Sanity entails dealing with reality. Honesty is about reality. It’s about admitting the truth to yourself and also admitting it to others. Honesty equals sanity. Deceit and pretense are bad for your mental health.
