5 ways narcissism makes people stronger, smarter, and more successful

• Narcissism in small doses can make you a healthier, more successful person.
• Scientists have studied the myriad benefits of being mildly narcissistic.
• Those benefits include greater life satisfaction, stronger relationships, and less social anxiety.

In his 2015 book, "Rethinking Narcissism," Harvard Medical School psychologist Craig Malkin adds some nuance to the conversation around narcissism. News flash: It's not all bad.

Malkin introduces the concept of "healthy narcissism," which means that you display some narcissistic qualities - but they contribute to, rather than detract from, your success in life.

He also suggests that narcissism isn't a fixed trait - you can display more or less of it at certain points in your life.

As it turns out, there's a growing body of research on the relative benefits of narcissism (though not all scientists use the term "healthy narcissism"). We checked out some of that research and highlighted the most compelling insights on how narcissism can change your life for the better.
