One of the few truly reassuring features of not-knowing among youth workers is the realization that not-knowing cannot last forever. Eventually, some feature of the situation shifts, and youth workers move back into the capacity for action. This chapter describes the last of five themes associated with youth workers' experiences of not knowing what to do: Not-knowing gives way to knowing. In addition to presenting the dominant theme, this chapter discusses the three variations on it, as described by youth worker participants: (a) The rousing power of someone else, (b) I have to respond, because no one else will, and (c) The power of winging it.
