听力原文:I cold-call a lot of customers, you know— just call up potential clients to try t
o make sales. Mainly when I cold-call somebody I try to set up an appointment— nobody's going to buy your product or service over the phone, you know? The key for me is to make sure I do some research beforehand, and try to add a personalized twist. Like I'll try to have some background on the company; ideally, I try to find any recent news they may have generated—that works really well as a conversation starter. If I can't find something on the company, I'll try to find something on the company's industry. A lot of times, I'll make them aware of an article they might be interested in. If they haven't seen the article, I offer to bring it by their office, and while I'm there, tell them about our services. At any rate, the cold-call gets my foot in the door, which is all I can really hope for.
