What is the Best Personality Profile? | Optimal Mental Health Personality on FFM

This video attempts to answer the question: What is the best personality profile?
Another way to think of this question is: What personality profile has the optimal mental health associated with it?

The answer is expressed using the five-factor model of personality (FFM). The FFM looks at personality as being in five big traits, sometimes they're called the big five. I remember them through the acronym OCEAN: openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism. Each of these five traits has six facets.
For example, with extraversion, we see warmth, gregariousness, assertiveness, activity, excitement-seeking, and positive emotions. To come up with a healthy profile, the article reference below used a number of instruments and experts. What is the healthy personality profile that they came up with? Simply put, its high openness to experience, conscientiousness, extraversion. and agreeableness, and low in neuroticism. Being more specific looking at the facet level, it's high scores and low scores on particular facets: openness to experience - high feelings and average fantasy; conscientiousness – high competence; extraversion - high warmth and positive emotions and average excitement-seeking; agreeableness - high straightforwardness and average modesty; and neuroticism - low score on angry hostility.
