i don't know how to say it

its going to be a hard and boring this week. i couldn't say what is my condition after 3 weeks of lectures & tutorial classes but one thing for sure that i'm a bit suprised, glad and lost! Surprised because after 3 weeks gone i am still having empty class besides chairs and annoying sound of the air-conditioner but NO STUDENTS!..Glad because this semester i got less teaching hours BUT its to early to confirm coz based on last semester's incedent at a very last minute & a very last tutorial weeks i got extra class. I feel lost coz i still dont know what sholud i work on my Ph.D proposal topic even though i have lots of ideas but no FOCUS!
