3. The motivators.  The aggressive approval-seeker

"Success is getting what you want. Happiness is wanting what you get."  - Dale Carnegie

Being admired is very important to 3s - they are competitive, and place great value on winning and looking good while doing it.  Publicly, 3s project high self-esteem, driving relentlessly toward their career and life goals.  But the average 3's craving for external approval may degenerate into superficial and image-conscious behavior, as they work hard to look impressive while neglecting genuine achievement.  Despite the high self-esteem they project to others, 3s may privately feel insecure about their self-worth, being as it is so dependent on what others say about them.  3s have an unusually strong inner contradiction; they project qualities of leaders: drive, energy, and success, and yet their definition of success is unusually dependent on the values of the society they belong to.  Hence, they are simultaneously leaders and followers.

Healthy 3s often have a "cool" attitude to go along with their accomplishments - they know what is "hot" and what is not, and for better or worse, this contributes to the 3's reputation for being excellent salesmen who can win over the most reluctant audience.  Because they place high value on affirmation from others, they may be very adept at reading subtle cues in others, using this information to quickly tailor their message to their audience.  However, unhealthy 3s are notorious for being phony and self-promoting.  Extroverted 3s can be charming smooth talkers, using their networking skills to augment their image and their career, which may be closely linked.  More introverted threes may instead strut their stuff through competence and skillful performance rather than showmanship.

American culture is probably a 3-ish society, with its emphasis on appearances, success, and winning.
