I keep going back and forth between this and INTJ, depending on the questions asked. Sometimes, though... Bolding the parts that are most relevant at the moment. This is mostly for my own reference.
You are: The Crafter (ISTP)
ISTPs are realists who apply expediency and reasoning as they manage and adapt to situations. They are aware of what is going on in the environment and are able to respond quickly to the actual facts, making sure the odds of success are in their favor. They do not like to be tied down and will feel hamstrung when they must operate within tight structures and schedules. They are able to anticipate immediate, practical needs in situations and to present a logical, straightforward plan for meeting those needs. They are at their best in situations that require immediate attention.
You are clearly an Introvert
You scored 90% in the direction of Introversion, which means you are clearly an Introvert. People who are clearly Introverts are reserved, quiet, and contemplative. They dislike the social pressures of large groups and being the center of attention, but are not necessarily shy. They frequently spend time alone in order to reflect and "recharge".
You are a Sensor
You scored 9% in the direction of Sensing, which means you are a Sensor. Sensors are sensible and grounded, focusing on the concrete and the here and now. They learn through experience and are cautious with untested ideas. They appreciate tradition, but are open to new ways of doing things if they can see tangible benefits.
You are a Thinker
You scored 36% in the direction of Thinking, which means you are a Thinker. Thinkers recognize the value of feelings but are more comfortable with logic and reason. They tend to be straightforward with others and are not easily offended. They often notice where there is room for improvement in a person or situation.
You are a Perceiver
You scored 5% in the direction of Perceiving, which means you are a Perceiver. Perceivers are flexible, adaptable and easygoing. They see all sides of a situation. They usually don't have too much trouble making a decision but prefer to leave things open for reconsideration if possible. They can make and keep a schedule, but generally find the whole process a bit restrictive.

Life:
ISTP children want life to be logical, flexible, and action oriented. While they like hands-on activities, they also may want to stand aside and observe what is taking place. They are especially observant of what makes things tick and may take apart a toy to see its inner workings. ISTP children are curious and are great gatherers of data and detail. They rarely forget what they have noticed about places and things. ISTPs observe their parents in order to find out if and in what ways their parents vary their actual behavior from what they say. ISTPs monitor the differences between what people say and what people do. They are aware of flaws and try to correct them.ISTP children become very absorbed in their hobbies.
ISTP teenagers may have several close friends but generally are not social butterflies. They relate to others by sharing detailed information about one of their interests or sharing in physical activities that involve a measure of risk. They like sports in which they can challenge themselves and master specific techniques and strategies. Bowling, skiing, wrestling, soccer, flight training, and wind surfing are activities that often interest ISTPs, because these sports involve a measure of risk and strategy.
ISTPs are willing to take charge of their lives and develop their interests, but see little need to do the same for others. ISTP teens often select part-time jobs that allow them to indulge their interests or hobbies.
As young adults, ISTPs tend to follow a path of least resistance when thinking about their careers. ISTPs are efficient types who find the quickest and most expedient way to get what they need. For example, a part-time job as a teenager may lead to a full-time job as an adult. ISTPs are pragmatists and gamblers who play each hand as it is dealt. As a result, they are able to take advantage of opportunities as they arise.
In adult life, ISTPs are fairly laid back and mellow. They do not impose much structure on themselves or others. Because they retain and use detail for logical ends, they are often recognized by their employers as people who do well with the careful and precise understanding of factual data. They are at ease handling interruptions in their work, and, in some cases, they become energized by the challenge of overcoming an unforeseen obstacle.
Mature ISTPs want a measure of flexibility and spontaneity in their work. They are able to combine work and play, often making games of the numbers and details that they manage. However, they become restless if they do not find adequate use of their interests in their work or hobbies. Most ISTPs, when questioned about their careers, reveal that they would love to have more time and income to pursue their interests full-time.
Because retirement may allow ISTPs to further pursue their work, as well as leisure, interests unhampered by time demands, it is a very desirable state for them. If their work is interesting, they may resist retirement because their work is a key element in their lives. When their work does not provide them with enough enjoyment and challenge, they may try to arrange things so that they can retire early and thus obtain more time to enjoy their leisure pursuits.
Work:
At work, ISTPs contribute their realistic and logical way of meeting situational requirements. They can see the easiest and most expedient route to completing a task, and they do not waste their effort on unnecessary things. They often act as trouble shooters, rising to meet the needs of the occasion. In many organizations, they get things done in spite of the rules, not because of them. Since many ISTPs have a natural bent in technical areas, they may often function as "walking encyclopedias" of technical information. ISTPs know the standards, specifications, and requirements of their work; they use this information in a calm manner, even during a crisis. At such times, they have a settling effect on others, because they know so much practical information and use it to "save the day. "
Work Setting
ISTPs prefer a work setting that is project oriented and unconstrained by rules. They want a chance to be active, independent problem solvers. They do not like routine but want the opportunity to be somewhat inventive in meeting current needs.
Organizing Style
The ISTP organizing style is based on expediency and quick application of information. They often organize their hobbies or collections and make a game of finding the best way to arrange things such as their rock collections, their spice cabinets, or their antique automobile magazines. In the rest of their lives, their approach to organization is largely incidental. ISTPs may not have a system of organization that is discernible to others, but through the use of their memory for detail, they can usually locate what they need at the time.
Occupations
To perform well at work, individuals may need to use all of the eight preferences at the appropriate time and when required by the situation. Knowing this, people tend to select occupations that allow them to use the preferences that are most natural to them.
ISTPs prefer flexibility and impersonal dealings with others. Because they often have a technical orientation, they prefer to work in an environment that produces a practical product. They pay attention to the organization's hierarchy only to the point of learning how to bypass or go around it if it stands in their way. ISTPs may have mastered the details of the organization (how everything fits together), but may rebel if it is too rigid.
While ISTPs can and do enter all occupations, some are more appealing to them than others. According to available research, some occupations (in alphabetical order) seem to be especially attractive to ISTPs: carpenter, construction worker, dental hygienist, electrical engineer, farmer, mechanic, military personnel, probation officer, steel worker, transportation operative, and other occupations that allow them to use their ability to act expediently. These occupations are not meant to be an exhaustive list, but serve to illustrate some areas that an ISTP might enjoy. If your specific occupation, or one that you are interested in, is not listed here, think instead of its general characteristics and ask yourself how those fit with your type.
Love:
For the ISTP, love means being responsive, yet realistic. ISTPs seek partners who either are willing to allow them to have their necessary freedom (especially for their hobbies and interests), or who will participate in these activities with them. They may introduce their partners to their interests if they are ones that they want to share. When this is the case, they will acquaint their loved one with all the facts and details of their interest.
When falling in love, ISTPs are very attentive to small things that might be enjoyed by their partners, surprising them with those particular gifts. They would rather show their feelings through their actions than verbalize them. They are not likely to discuss their feelings about their relationships with their partners (and almost never with others) because they believe that the experiences that they have had together will speak for their feelings. Feelings are discussed only when necessary.
When scorned, ISTPs are not likely to share their hurt feelings with the external world. If the couple still has some interests in common, ISTPs may maintain the relationship with the loved one, but on a different plane. They do not give up easily on their relationships, however, unless the weight of the factual evidence convinces them to do so. When the relationship is actually over, they are usually not vindictive. They see the end of the relationship as a concrete fact about which it does little good to worry. They can therefore move on to new experiences.
