I worked in a job that required me to occasionally cold call businesses for information. I always felt like it was a terrible inconvenience even though they expected it, I suppose.
I would have to psych myself up for it. In addition I would be sure to have exhaustive notes and specific wording for questions so I wouldn’t feel like a complete idiot when I called.
I was younger than the call recipients in most cases and always had this fear that they would just think I was a young idiot, so that went into my exhaustive prep.
I have no problem calling people I know. Just cold calling strangers puts me on edge.
If I had ever had a job as a telemarketer of any kind, I would have starved to death.
