Rhyme, those are great choices. I, too, struggle with a back-up. I also struggle with the notion of not having a back-up. I guess I'm fortunate enough not to 'need' an MBA, but I would really like to get one for the extended future. The short-term benefits for me will be minimal. Salary-wise, I probably won't make any more post-MBA than I make now. I will be on the older end of the scale and if I don't get in, I'll probably consider the Executive program, which I will be eligible for in about 3 years.
That being said, it would be a real bummer to go through this entire process and not come out with any tangible benefits. I, myself, am thinking HBS, Stanford, MIT, and two others. I'm big on being in a city that I want to live in - I lived in Boston for many years, so it's my first choice in cities. I'm not really a 'New Yorker', Chicago is not bad, Hanover,NH would be awesome, but I would prefer to be in a bigger city. Philadelphia's ok, its main perks being that it's close to NYC and DC. I wish Georgetown had a better ranking and reputation. I'd be content staying here in DC. I've been looking at not only rankings but what percentage of applicants they let in. For example, I work with lots of people who went to Darden. It's very well-regarded in my industry, top firms recruit there, yet they let in almost 50% of applicants! Maybe that could be your second-tier? Or even Duke.
Yale is also up and coming so I wouldn't be surprised if it cracks the top-10 in the next several years. I have friends who have gone there and are very successful. I'm a huge New Haven fan.
What do you do for work now?
