You only have one life.One life to be the best you can be ,one life to be remembered by, one life.I am in love with the violin. i am in love with medical things. My mom died from cancer when i was 13 andi havnt been the same since. She told me that i could not play the violin so i got private lessons i am one of the best in my orchestra since then all i wanted to do was play music i loved the way it made me feel. But my feelings changed fast when i discovered the human anatomy. at first it was hard to watch medical things because of my mom.But i started watching shows like scrubs and greys anatomy and house and loved them.. i love the lab coats i want to save peoples lifes i want to be a seargin i understand the school that u have to go threw the debt i will be in i understand.
