Adults have their own “boogeymen”—the unknown, rejection, failure, success, and so on. And these boogeymen should be a sign to take action as well. For example, if you're afraid to call on a client, then it's a sign that you should call that client. Fear of speaking with the boss is an indication that you should march into his office and ask for a moment of his time. Fear of requesting the client's business means that you must ask for the business—and then keep asking.
