ISTJ

based on Jungian Typology, i described as..

ISTJ
Introverted Sensing Thinking Judging

and the description is..

ISTJs thrive on organisation. They keep their lives and environments well-regulated. They bring painstaking attention to detail in their work and will not rest until satisfied with a job well done. ISTJs are faithful, logical, organized, sensible, and earnest traditionalists. They earn success by thoroughness and dependability. Shutting out distractions, they take a practical, logical approach to their endeavors. Realistic and responsible, they work steadily toward their goals. They enjoy creating order in both their professional and personal lives. ISTJs are persons of thoughts and (sometimes) emotions. They prefer dealing with the present and factual, using various options to make decisions.

and you know what.. it's a damn accurate.
