Example one: You work in an environment where you are the smartest out of the group. Everyone turns to you when there is a question or when advice is needed. The down side is, when you step outside of this environment, it hits you. You’re not as smart as you thought you were. Your work place just happens to be filled with the mentally less fortunate people. Example two: You work at a prestigious University and everyone around you is always at the top of his or her game. Seemingly, out-thinking you, resolving problems much faster and much more efficiently to you would ever imagine. The down side is, you always feel unintelligent. These two are just examples of what the difference would be. You can also relate this to your spouse vs. work environment. Or being around kids vs. adults. etc. How would you like to live?
