Postgraduate studies

I honestly have a big doubt about what I am going to do when I graduate, i was thinking about a Master, maybe in Arts or Urbanism, I dont know yet, i have always had this big paradigm of being happy or helping the humanity getting better, i hope I can do both, art is something that makes us stay alive, but there are more essential things that big part of the world dont have the oportunity to have, and that is so unfair. Master in arts or urbanism, there is the dilemma, but what Im really sure about is that i want to study in another country, maybe France, Italy, or the only city that i would go in the Unites States New York, the dream is going with a scholarship but if that is not poSsible maybe a part time job would help a lot while studying,i know it's hard work, but I'm sure it will be worth it.Studying in a university of another country would be awesome. I believe if i do a Master's in Urbanism, or maybe Sustainability in Arquitecture, that's what I really want to do, Sustainability in Arquitecture.How Arquitecture is influencing the world and the people in the wrong way, how to make solutions for the problems that we have nowadays. Helping the progress in a way in a different country and our own.
