The Four Most Difficult People You'll Ever Manage

4 Quadrants

1.  Relators - Hate confrontation/conflict.  Relate to people organically. 

2.  Socializers - Make everything fun.  Downside, they sometimes have too much fun and aren't taken seriously.

3.  Thinkers - High thresholds for analytical processing.  They take sometimes too long to make decisions.

4.  Directors - Desire efficiency and productivity from team.  Sometimes they get these things through a lack of effort and respect toward team.
