Everyone gets cold call anxiety. It just becomes more tolerable through experience. Honestly the best way to get through those nerves is to simply "Pick up the phone and start dialling" Exposure to cold calling will make you realise your thoughts were making cold calling out to be this big bad beast but in reality its not bad at all. Quite enjoyable actually. Only thing I keep top of mind when dialing is "Do not perceive the decision maker as above you in any way"
