The first part of the chapter is more concerned with movements, social pressure the power which is contained in weak ties, and the social habits formed by friends. According to Charles, step one of the movements is usually the action of moving which begins as a result of strong ties within acquaintances (Duhigg, 2012). The second step of movement occurs when the movement now grows due to the habits formed by the community, and as a result of the weak ties which hold it together. The third step is the one in which this movement endures because the leaders in the community provide a platform for the participants to have new habits, and as such create a sense of ownership within this particular movement.
The second part of this chapter deals with the social habits, mainly of peer pressure, weak ties as well as the growth of a movement. The author states that peer pressure among acquaintances is spread through weak ties, and they are strengthened through the communal expectations. The third part of the chapter concentrates on the social habits in relation to the sense of community. This is present in the case of the Saddleback Church which appeals to the social habits of this particular community (Duhigg, 2012).
