He seems so bland than what I envisioned him. Oh well.
"According to Myers-Briggs, ISTPs excel at analyzing situations to reach the heart of a problem so that they can swiftly implement a functional repair, making them ideally suited to the field of engineering. Naturally quiet people, they are interested in understanding how systems operate, focusing on efficient operation and structure. They are open to new information and approaches. But contrary to their seemingly detached natures, ISTPs are often capable of humorously insightful observations about the world around them. They can also be closet daredevils who gravitate toward fast-moving or risky hobbies (such as bungee jumping, hang gliding, racing, motorcycling, and parachuting), recreational sports (such as downhill skiing, paintball, ice hockey, and scuba diving), and careers (such as aviation and firefighting).
ISTPs may sometimes seem to act without regard for procedures, directions, protocol, or even their own safety. But while their approach may seem haphazard, it is in fact based on a broad store of knowledge developed over time through action and keen observation. ISTPs enjoy self-sufficiency and take pride in developing their own solutions to problems.
ISTPs are content to let others live according to their own rules, as long as the favor is reciprocated. ISTPs endure reasonable impositions without complaintóbut if their "territory" is encroached upon, eroded, or violated, they defend what they view as rightfully theirs."
