I am often reserved and quiet. I plan ahead and tend to follow the plan. I am concrete, materialistic, realistic and practical. I seek fewer but deeper interactions with people. I appreciate ordered systems and structures. I dislike changing my own decisions. I often wonder about the past or the future. I quickly explore and get familiar with new places. I am often hesitant and doubtful. I like to observe and study other people and their relationships. I subject everything to logical analysis. I am often immersed in my own world of thoughts and feelings. I feel very confident with all aspects of logical reasoning. I flee rather than talk about feelings. I do not know many people. I often feel bound by my own promises and appointments. I am ok with dealing with strict rules and guidelines. I am attracted more to the theory than to its utilisation.
