Pharmaceutical Question:

A person who is new to the world of pharmaceutical sales will most definitely point out that the most difficult part is meeting the medical practitioner, but that is actually not so.

The most difficult part is actually convincing a doctor to switch from a drug that s/he and their patients are quite comfortable with and present a new alternative, which may or may not be better. Of course, the target group of a pharmaceutical is quite different than a common salesman, but that is the least challenging aspect of a pharmaceutical sales rep.
