Congrats on getting accepted!
Two hard choices to make. First, I recommend watching a TED video by Ruth Chang "How to make hard Choices" It will give you a new perspective on how to decide. (Didn't link, not sure if it's against the forum rules)
I casted my vote to UNC. The reasoning is because of the full scholarship. 120K debt + the extra cost of living in NY vs NC is going to be huge. You know, people say 'you will make it up within 10 years.. etc etc.' but no you won't you dont' know how it is going to turn out. This is not a logical way of thinking. You cannot make this argument. They are both solid choices. I will explain to you why going with the full scholarship is the better choice.
Would have been great if you got in both with no scholarships to make the choice easier, but a full scholarship is a crazy good deal. The amount of interest on debt from NYU is going to be crazy. It seems like you might be leaning towards NYU and if I was in your position, I would too. But a full scholarship is going to make all the difference. Graduating with no debt will make your life so much easier. You will have the freedom do anything you want, while if you graduate from NYU with debt, your choices on how you want to live your life will be limited because of the mounting debt on your mind.
For example, lets say you graduated you have no debt. Oh you want take a break and travel world? You can. You want to go full time in your own business, although it doesn't make money? you can. You have 2 choices of jobs one that you love, but dont pay well and one that pays well but is going to leave you stressed? You can make the choice of going with the less paying job.
When you graduate with 120K+ debt. The answer to every single question above is. 'Hmm.. I don't think so.'
NYU is a fantastic school and of course if you do decide to go there, you are going to have a great time, you will have a great job and you will not regret the debt for choosing NYU over UNC. However, you should understand that if you make this choice, your decisions on life choices are going to be limited, because of your debt.
'traveling the world right after your MBA' is not a good idea either way, but at least with UNC you have the freedom to do so if you really really really wanted to. (bad idea though, but still). You have your own business and you will have the freedom to decide to keep doing that if you want. OR you might be inspired to do another startup while at school, and you can do that if you want. If you have 120k debt you have to pay a minimum of 1k a month...
With NYU, you will be limited to taking the traditional path.
Freedom vs. Tradition is choice you need to make. If you choose NYU really really do the math and understand what you are getting yourself into.
PS: interesting perspective is do you want a piece of paper that say MBA? or do you want a piece of paper that says MBA and a fully paid for Benz S class AMG?
Is the upgrade from UNC to NYU worth a fully paid for Benz S class?
Either case good luck. I know I said go to UNC, but both are solid choices. You wont regret either way.
Let us know where you end up going.
/Kudos!
