you don't need to have dreamt about being a doctor since you were a little child to study medicine, but you do need to LOVE it. my mum is a doctor, so i have always been familiar with this profession. many people think that medicine is a very beautiful profession and it is, but once you decide to become a doctor, you have to devote your life to it. you will have to study like crazy in college and you will have to work like crazy after you graduate. you can have a family, friends, hobbies, obviously, but they will always come second in your life (i know this because of my mum, she lives for her profession). medicine is one of those professions which you must take as your mission in life.
