The first day

This is the first day of my MPhil study in the University of Hong Kong, Hong Kong. It demostrated that my life as a young researcher in the place far away from home has began. The twisted feeling makes me sorrow. It may be the low efficiency in working. Only finished the notes of the first chapter of the book makes me blue. The chapter is easy and I should have down more since I have read the part before. But I don't know which parts should be presented and which should be omitted in presentation and left for reading. It's so hard to decide without the requirement on time. The weighing precedure and slides making with Beamer costed me too much time. Letting alone the time I was absentminded and did nothing. Will I do the presentation well for this week? And can I read enough books to meet my own requiremnet? I don't only need to read books but also so other stuffs, can I make the most of time? I doubt. It may be the TA which I don't know if I'm qualified. I don't want to just copy my solution on the blackboard and say "this..." and "that...". I want to leave good impression. But can my "long time no use" satisfy the undergraduate students who even speak better English than me? Is my digital communication background good enough for me to provide not only the correct but also the quickest solution? I really need to check it out starting from tomorrow. It may be the reason of my home sick. I kind of miss the life at home eating, sleeping and watching films with Chinese subtitles. But I know I also had familiar feelings when I was in HUST, and it doesn't help me to get out of feeling low. So I should just send Mum my very best wishes and cheer myself up. What am I here? Will I feel happy here after some time? Can I find the real me here or just continue being confused after graduation? I wonder. I hope I can quickly find answers for them, the answers of the first day of a new era of my life.
