Business is personal. And the two groups of people you have to worry about the most are your employees and your customers.
Here's a little secret from my past: One of my first jobs after college was in a supply house. The company wasn't in the PHCP industry but was a cigar-and-candy wholesaler in Nashville.
The owner hired me to clean up in the warehouse, and apparently I showed such talent at throwing away garbage that he promoted me to work in the back office. He was grooming me to cover a sales territory, but I didn't discover that until after I gave notice. I wanted to go back to school to get a master's degree in journalism.
