IJ, or Balanced-Stable Temperament (Introverted, Rational, Static)

These types are able to focus their attention and move deliberately toward a predetermined goal. This is supported by their psychological composure, patience, and endurance in executing their plans.

How are these qualities exhibited in a healthy personality?

Patience: This is more than just maintaining composure in an unfavorable situation or controlling one's feelings and emotions; it's also the capacity to resist one's own aggressiveness toward others.
Composure (or Self-Control): A composed person knows how to weather life's setbacks, manage their mood, and avoid impulsive actions. Even in extreme circumstances, they maintain their presence of mind, remain cool-headed, and can stoically endure all troubles and adversities.
Endurance (or Stamina): The stable, consistent ability to resist fatigue, enabling the continuous, steady, and regular performance of work without a noticeable drop in efficiency.
Diligence (or Assiduousness): Diligence is applied to prolonged, sometimes unpleasant, tasks. Because this effort stems from a rational assessment—a "necessary versus unnecessary" mode—the individual will perform their duty meticulously, earnestly, and responsibly. It is the ability to show great effort, zeal, and responsibility for the results of their labor.
Frugality (or Thriftiness): The capacity to maintain a reasonable measure when expending any resources.
Concentration (or Focus): The ability to be completely absorbed in a task. This involves skillfully maintaining and focusing attention while simultaneously abstracting oneself from all external distractions. It also implies heightened self-possession, self-control, and prudence.

But how do we characterize a person whose Ego-block is suppressed?

This suppression is primarily associated with a lack of a sense of foundation. It's as if the person has nothing stable to rely on. Their self-esteem crumbles, leading to complaints like: "I'm useless, I can't do anything, I don't know anything." The person begins to whine and lament that they are stupid, weak, and so on.

Alternatively, they might exhibit the opposite extreme, marked by traits like selfishness, stinginess, stubbornness, coldness, unsociability, conservatism, dogmatism, and cruelty. Such individuals become withdrawn. When asked what's wrong, they respond coldly: "Nothing!"

This behavior doesn't appear as a cry for help. Instead, it seems like the person has resigned themselves to defeat, believing everything is over. These individuals are almost always tense; they struggle to understand others, find it difficult to connect with them, and cooperation is even harder. It's as though they desire their most negative fears to be confirmed, and they feel irritation or even anger toward anyone who tries to convince them that all is not yet lost.
