I guess that each culture has its own problem to face. As an Haitian, there are only three prefession that a young persons should pursue: Medical Doctor, Lawyer or Engeneerer.
After high school, my dad adviced me that I should go to Med School. I told him that I was not interested in med school, because I know that bio and chem were not my subject.
I went to school for Business Administration, I had an Economic professor, he made me fall in love with the science of economic.
But, I was thinking of switching my major, then I decide to graduate in Management instead, and go for my MBA.
By the way, I have my MBA, because it was a must for me to have a graduate degree. After that I was still confused by thinking that whether I should apply for a Ph.D in Economic, or International Relation. I started making reseach about Law, and I ended up loving everything about it. here I am trying to get into law school. Nevertheless, for the Ph.D in Economic, the dream is still there, because I must have it, and I believe that it will be good conbination with law.
Anyway, I was a rebel to my dad, I did things my way.
By the way, a JD (Juris Doctor) is still an undergrad degree, the original name is LLB (Bachelor in Law). in the rest of the world, they have LLB instead of JD. After your JD, if you want to go for a Master, you will need to go for LLM (Master in Law Science). you can also go for your doctorate in law, it is SJD (Doctor of Juridicial Science.
