There are many people who have different thoughts/opinions etc...who always forced others to walk like what they want .Amna in my personal view there is no job which is good or bad,if you need/want job then this job is best for you.I strongly recommend you to go for this job without dishearting yourself yeah caravan is also good but i like Jhangir Encyclopedia of MCQ;s....and its perfect for FPSC/ppsc like Exams.
