In the time of telemarketing, before the 1-800-stop-calling-me-number kicked in, I was a telemarketer. My job was to close as many sales as possible in six hours a day, to make every call a sale. The trouble with goal-oriented sales is that it is very depressing, at least it was for me. Cold calls seem to always result in more "No's" than "Yes's." If my success was defined by whether or not a customer said yes, then I quickly became a failure.
