It doesn't include stackings, but I find this site's variant descriptions to be rather useful (I even solidified on my own variant based on them ):
The Achiever (the Three)
Achievers try to be seen in a good light, according to socially agreed-upon norms.
Self-Preservation Threes: "Security"
- Financial security is of the utmost importance to me.
- I need to keep physically fit and stay in good health.
- I continually learn new skills and keep up on the latest developments in my field in order to achieve and hang onto my career goals.
- I'm a good team player; I try to get along and stay away from conflict.
- I rarely take time off; when I go on vacations, I often take my work along.
- To me success doesn't necessarily mean being a leader or the center of attention. The person I'm trying to compete with and please is me.
- Threes of this subtype are usually less extroverted and less concerned about image than the other two subtypes are and may be difficult to recognize as Threes.
Relational Threes: "Masculinity and Femininity"
- I try to impress the opposite sex with my charisma, success, sexiness, and strength.
- I have mastered the art of looking attractive.
- I pay great attention to what others find appealing and dress accordingly.
- I alter my behavior however I need to in order to keep my partner attracted to me.
- I want to be envied for having a great relationship with an admirable or prestigious person.
- I will avoid pursuing someone if there's a high chance of failing.
- I fear that people may want to reject me when they really get to know me.
- Threes of this subtype often resemble the relational subtype of their Six arrow.
Social Threes: "Prestige"
- I am an energetic, efficient, and strong-minded leader. I motivate people to do a good job, find clever solutions to problems, and I keep my audience's attention.
- I am proud of my friendships with other successful and powerful people.
- The organizations I belong to provide me with good opportunities to further my success.
- I get along in groups that are very different from one another.
- The way I fit into such disparate groups is by changing my personality and attire to meet the situation.
- Credentials, titles, and degrees are important to me.
- Nothing would be worse than to be anonymous.
- As a thinking type, I tend to focus on the group's goals. As a feeling type, I try to maintain harmony among the members.
