Graduate Degree- A challenge, a new experience!!

I am now a 2nd year graduate student of a well known University of my country. Most of my friends told me that I am so lucky that I have given a chance to pursue my studies as  a scholar at my present school. Yes I agree, but sometimes I am so tired and bored of studying I even felt very stressed out. I keep on asking myself if I have to do this , because I just want a SIMPLE LIFE..!! One of the reasons also is  I  miss my parents a lot and I am longing of them already in which I usually found myself crying at night.I am not used to be apart from them, thats how much I love them. How will I cope with that situation? Hmmm I just pray to God, and think of the privileges and opportunities that God had given me...and telling myself that "all of these are for my own good, for my better future"--and then I felt okay!!!! :) Yes, I truly agree that I am so blessed because I know that many of the people out there wants to pursue their studies but they cannot. That's why I am bringing back to God all the praises and honor.
