School life, No more?

Very hot and boring afternoon..Tomorrow it is the last exam for the semester but still could not really settle down to do some last minitue reading..well,I guess since 18 years ago, I have been with school, lessons, exams all time along. Although a year working in US could have added some excitment in my life, i still feel that i am living in a school environment.Yet,I have not made up my mind in pursuing a PhD.

Should I?
