Never ask for, or accept, a person’s name or number on a business card. A name on a business card is not a referral – it’s a cold introduction. The next time a contact hands you someone’s business card and suggests that you call because “they may be interested in what you do”, suggest that they arrange a meeting for you. Personal introductions will always trump cold introductions, and you should strive for this level of commitment from others who express an interest in you.
