Self-Control. In the average range, Self-Preservation Ones tend to worry about their material well-being, both in terms of finances and health, and they often castigate themselves for not working hard enough (like average Sixes). The Self-Preservation instinct also gives them strong drives for gratification, but their Type One superego can be severe in countering those drives. The resulting inner conflict is the source of continual stress, physical tension, and an all-or-nothing attitude with regard to their pleasures and desires. They may either indulge themselves and their desires, or go through periods of asceticism, during which their desires are suppressed as much as possible. As they become more identified with their superego dictates, they become very fearful about making mistakes that seem like catastrophes to them. They feel that any wrong action could result in the undoing of their well-being. They can be quite picky and fastidious about their environment. (Picture Felix Unger in The Odd Couple.) They value cleanliness, order, hygiene, and aesthetics, and they are often preoccupied with health and diet, religiously subscribing to beliefs about vitamins, macrobiotics, homeopathic remedies, and so forth. With others, they tend to be overprotective about the things that they worry about in themselves. If they are worried about getting sick, they scold others about not taking care of their health. If they have money concerns, they exhort others to save. In the lower Levels, the harshness of their superego causes them to feel undeserving of any kind of comfort or reward. In the unhealthy range, Self-Preservation Ones begin to oscillate be tween periods of strict restraint of their appetites and periods of excess and debauch. They often become obsessed with health matters, especially with regard to food. They often attempt to justify or undo their violations of their own dietary or health requirements. They may binge on sweets, or drink excessively, then goon a crash diet. Milkshakes and fries are fol lowed by handfuls of vitamins. Self-Preservation Ones are prone to eating disorders and extreme practices to curb their instinctual impulses, including asceticism, excessive fasting, binge eating and purging, and so forth.
