post-graduate studies

in this moment i don't know which study of post graduate I want because for this i need know which speciality i want and .. i dont know this.
i imagine in 5 years more i will love one speciality and i will choose a postgraduate studies that have relation with this .. ok now i will imagine that i know what i want and i will chose a postgraduate studies about pediatric dentistry for whrite this blog.
if i wanted a postgraduate studies about pediatric dentistry , i would it abroad , i will like in USA or europe , specifically in france or italy because i love these countries.. and if i lived in another place i would like to know besides studying. i think that postgraduate studies are very important because only one degree is not sufficient and it is very important continue the studies for be a big professional. i think that the best study method is presencial class , more than online classes. If i studied abroad would be very funny, i would want go studied abroad with some friend and travel around the world while we study. This would be like work , studied and travel . all together .. the best future !! ok .. if not possible study abroad , i would study here in chile , in the UC university or university of chile and i would be trying to perfect myself always , this is very important. it does not matter if you study here or abroad, the important thing is always to perfect yourself and try to be the best professional.
