Can't find my goal yet

I am a person who don't like to do sharing. yesterday was another breakthrough because I did sharing in front of 30 plus people again. so so long never do sharing. actually I am in dilemma again now. I don't know whether I should start it at this moment as I am in my final semester now. I really can't fail at this level. kinda sad today because first day of class after posting for six weeks and I was late. but I still went into the class and fortunately lecturer didn't scold anything. also I am not really sure is this suitable for me? what about my air stewardess dream ? what about my dream working overseas with my gang of friends after graduate? how I wish I have many many lifes...
