Friendship is sacred, networking is profane. By networking, I mean working with, rather than against, the fact that career success depends more on who you know than what you know. Networking in this sense means sizing people up as useful or not, as assets or liabilities, and budgeting your social time accordingly. Friends are the people you want to spend time with, rather than people you "collect" in a Rolodex™. Friendship is non-transactional sociality.
