Since I was a little girl I've always dreamed about becoming a Doctor, though I have no idea what made me feel that way. Maybe I realize about all the help a doctor can give... and I got in love with the idea.
After that, I had a few hesitation about it in high school, because I'm really good at math and physics, but I'm not that good at biology and medical stuffs. However, I realize that enjoying what I wanted to study was more important than being already good at it, and as I couldn't see myself as a engineer, chemist or anything else but a Doctor I discovered I had made up my mind.
And now I think what motivates me to keep studying is what I'm going to be when I graduate. I mean, I'll be able to heal people!! to know why and how people gets sick, and at the same time I can do something about it! It think accomplishing that deserves all the hard work I must do now.
