Some entrepreneurs who have tried cold calling in the past refuse to try again because of the high frustration levels. But as in learning any skill, practice can make you a better cold caller. Trial and error can help you discover what approaches work best for you. If you are reluctant, consider hiring a professional agency to make cold calls on your behalf. Listening in can be instructive and may give you the confidence to start making calls yourself. Above all, maintain a positive attitude and a belief in your ability to meet the needs of the person on the other end of the line.
