A Journey of Searching The Real Me. (PART 2)

I'm going to graduate in Diploma in Business Studies and maybe going to further my studies in this area too. But why do I choose this as my career? I DON'T EVEN KNOW. I don't have any talent in speaking in front of lots of people, I'm so nervous when it comes about presentation or giving a speech or whatever things like that. It isn't that my English is so bad so that I'm scared to talk in English, it's just because, I'm so LACK IN CONFIDENT. My confidence level is so low. I noticed that, I try to improve myself but I just don't know how and where to start. I need direction, I need someone to guide me. Can't anyone help me? :(
