"one question your career counselor asks is whether you have a network of professional contacts. you work out regularly at your local gym. you have had a few casual conversations with jim, who is usually working out when you’re there. you don’t even know jim’s last name, but in your talks, you have learned he is the supply chain manager for a local manufacturing firm. he is also friendly and always eager to talk with you. should you identify jim to your career counselor as a potential member of your professional network?
