I am so confused with life!!! What do I want to do?

I am sure that everyone in life has those moments where they are confused of who they want to be or what they want to do as a career. That is where I am at for the past few weeks. I think a big reason is because I am a freshman college student, or it may just be because I want to do so much. When starting college, I thought I wanted to try the medical field (typical Asian), but I realized that it takes too long. High school and college are completely different. In high school I was an A student and now in college my grades range from A-C's. However, I know that it is all my fault, but I do not know how to snap out of my lazy/procrastinating attitude. Just about everyday after classes, I go home and go online, checking my myspace, facebook, emails etc... Then just recently, I have been really fascinated with the Asian culture. I love listening to Asian music, mainly pop, such as Fahrenheit, DBSK, Raine Yang, Cyndi Wang, Nicholas Teo, etc... After learning more about Fahrenheit, my old dream of becoming a singer resurfaced. I learned that Aaron Yan in Fahrenheit was selected to become a singer/actor because a comic production company was looking for someone big on blogs and found him. I know that not everyone is as lucky as him, but still I am going to do my best. Sadly though, I am starting a bit late because I am already 19 and typical singers/actors start around their teens or early 20s. Overall, I want to be an Asian singer, which means that not only do I need to learn to speak more of my language which is Chinese, I will need to learn Mandarin and learn how to read/write it. I know that the road to fame is a gamble of luck, so I am going to continue attending college to get a degree in something, so at least I have an education to back me up. I am also considering in about 2-3 years to go back to China to go to school there to learn more about their culture and who knows I might find a career I like over there? Do I sound like I am living in a dream? My family keeps telling me that I do not have the breath/voice strong enough to go far, but I still want to do what I love doing. I am at a big disadvantage though because I do not know how to write my own lyrics and I do not know how to create my own music. However, I really do want to learn how to play the piano though. Well, this is my first time posting on my blog, which means I am a newbie, but still I hope I meet lots of people online through this blog that will be my friend! I am not sure what people write on their blogs, but I just figured that I would write my thoughts down like a journal. I am out! Bye!
