Some applicants may ramble on about themselves in a manner that may appear self-indulgent and not very appealing to the committee. Remember, this is an application essay, not an autobiography. Conversely, some applicants tend to say too little, perhaps hesitating to promote themselves too explicitly or not knowing what about themselves would be interesting to people whom they don't know. In such cases, perhaps focusing more on what you want to do than on what you have already done (let your record speak for itself) may help in getting beyond self-inhibition.
Here, as with Don’s false identity and (literally) meretricious mother, Mad Men keeps telling you what to think instead of letting you think for yourself. As I watched the first season, the characters and their milieu were so unrelentingly repellent that I kept wondering whether the writers had been trying, unsuccessfully, for a kind of camp—for a tartly tongue-in-cheek send-up of Sixties attitudes. (I found myself wishing that the creators of Glee had gotten a stab at this material.) But the creators of Mad Men are in deadly earnest. It’s as if these forty- and thirty-somethings can’t quite believe how bad people were back then, and can’t resist the impulse to keep showing you.
