ISTJs are quiet and reserved individuals who are interested in security and peaceful living. They have a strongly-felt internal sense of duty, which leads them to be very hard workers, who do not allow obstacles to get in their way. They do not usually give themselves enough credit for their achievements, seeing their accomplishments simply as the natural fulfillment of their obligations. ISTJs have an excellent ability to take any task and define it, organize it, plan it, and implement it through to completion. ISTJs are very loyal, faithful, and dependable. They place great importance on honesty and integrity. While they generally take things very seriously, they also usually have an offbeat sense of humor and can be a lot of fun. ISTJs have tremendous respect for facts.
Strength : Preserving
ISTJs are the most attentive to the details of what they experience. Possessing increased sensory acuity to their own experience, they are likely to remember many of their past experiences. Their past, therefore, acts as a guide for the present.
This trust in the past and in the way things used to happen gives them the most stable life possible. By repeating what has brought them comfort in the past, they achieve the security and certainty they cherish so much. Their natural discipline allows them to maintain healthy lifestyles and overall good health. Their sense of duty and responsibility makes them trustworthy people.
Their sometimes serious appearance could make others forget that ISTJs are the pillars of society. Without them we would lose our traditions, our cultures, and the most essential values on which we are built upon.
Immature use of this strength can lock the user into an impenetrable comfort zone, depriving them of any changes that would be beneficial to their life, as well as an obstinacy to toxic habits.
Developement Point : Innovating
ISTJs have the fear of all the possibilities that the future holds. ISTJs love facts and structure. Perfectly aware of the way things were, they demand that they remain so in order to keep a firm grip on reality. For this reason, reality alternatives are seen as the storm that tries to bring down the castle—a flood of ideas that, if some of them were true, could then change the facts and what is known—thus causing them lose control over reality. The madness of change in innovation is therefore the nightmare of these individuals.
They are so anxious to keep things in place and find the pace of life that gives them the most stability that they find it difficult to objectively evaluate the concepts that are embedded in harsh reality. Their view of the world is so rigid and fixed that linking facts to make assumptions, or even suggestions of what might be true, is a major challenge for them. Their use of innovation often be immature or childish. Most of the time, they will not give in to any suggestions or be overwhelmed by their unrealistic assumptions, which often boil down to simply imagining the worst possible scenarios—subsequently causing them to be blamed for their pessimism.
In their professional or sentimental life, they will be blamed for not being open-minded enough. You won’t find anyone more stubborn than they are when it comes to making the slightest change in their lives. Don’t try to change the time they get up, their favorite food, their favorite shows, their dress code, the place of their desk, the way they drive, their routine, or their traditions, because you won’t succeed. As a result, they may be very anxious and suffer heavy failures in an environment (professional or not) involving frequent changes.
One will be very astonished at the behavior of ISTJs when some of them will manage to make their weakness conscious, for they will suddenly become the most unpredictable and imaginative individuals you know. No barriers of thought will limit their imagination, from which will flow many objective insights into the world. For their vision of the future will be so precise that they will know how to guide you in your life better than anyone else.
ISTJs assess the longevity of a potential relationship with their crush by asking personal and practical questions. Leave space for them in their schedule and even agree to go against their plans when their crush need their help. Listen carefully to their stories and remember the details they’re made of. Never betray them.
ISTJs need someone willing to commit to a lasting relationship and who promises to always be loyal. Someone who respects ISTJ’s habits and ways of doing things and does not try to change them. Someone who is competent, not overly emotional, and who dares and takes initiatives to give them new and exciting experiences.
Once in a relationship, ISTJs are one of the most loyal partners one’ll ever know. Traditional and very serious about relationships. They will support their partner and help them achieve their goals while taking care of their safety, comfort and health, so that they don’t have to worry about anything but their objectives. Not the most romantic, but they are definitely the one you can count on.
