If you want to lose weight, the most difficult–and most important–step will be starting your new diet and exercise routine. However, you shouldn't overwhelm yourself by focusing on the total amount of weight you want to lose. Instead, set a smaller, more achievable goal of losing 10 percent of your current weight. When you successfully accomplish that first step, you can then set another goal to work toward. To lose that first 10 percent, you'll need to reduce your portion sizes and exercise regularly. You don't have to give up your favorite foods; instead, eat them in smaller quantities, and eat more slowly to enjoy every bite. If you do succumb to the temptation to overeat, don't give up on yourself. Accept the fact that you'll make mistakes, and resolve to resume your diet. Ease into a daily exercise routine by starting slowly and gradually increasing the duration and intensity of your activity. Finally, remember that it will take a while to form new eating and exercise habits. Give yourself time to adjust, and celebrate each time the scale tells you that you've lost a pound.

In оne tribe in New Guineа, аggressiоn is encоurаged in boys from early infancy. The child cannot obtain nourishment from his mother without carrying on a continuous battle with her. Unless he grasps the nipple firmly and sucks vigorously, his mother will withdraw it and stop the feeding. In his frantic effort to get food, the child frequently chokes-an annoyance to both himself and his mother. Thus the feeding situation itself is "characterized by anger and struggle rather than by affection and reassurance" (Mead, 1939). The people of another New Guinea tribe are extremely peaceful and do everything possible to discourage aggression. They regard all instances of aggression as abnormal. A similar tribe-the Tasaday of the Philippines-has been discovered. These people are extremely friendly and gentle. They possess no weapons for fighting or food-gathering; in fact, they are strict vegetarians who live off the land. Evidence of this sort suggests that, rather than being basically aggressive animals, humaÒT§ÄÝ>C n beings are peaceful or aggressive depending upon their early childhood training.
