The term cold is from Old English cald (Anglian), ceald (West Saxon) "producing strongly the sensation which results when the temperature of the skin is lowered," also "having a low temperature," from Proto-Germanic *kaldjon; source also of Old Frisian and Old Saxon kald, Old High German and German kalt, Old Norse kaldr, Gothic kalds "cold."

Cold calling customers is arguably the most difficult call to make. Some items to take into consideration; focus all of your questions on your client, not yourself, plan all of your questions in advance, don't follow any cold calling scripts, don't overwhelm your prospect during first meeting, don't attempt to sell on your first cold call, keep your prospect relaxed. Cold calling starts with a low temperature. The goal is to increase the temperature. Learn about yourself. Learn about your customer.
