It can be stressful as an 18 year old filling out a college application trying to decide what major you should pick. You've heard the horror stories about choosing the right major the first time because if you switch majors you won't graduate on time. At 18 years old I chose to come to Radford University as a pre-nursing major and at 19 during my first year of college I changed my major and I am now earning my bachelor's of science in Biology.
Changing majors is not as bad as it sounds. If you truly hate something or want to go for something bigger then changing your major is the right move. I decided I wanted to be a doctor instead of a nurse so I changed my major and started researching medical schools. I've had friends start as business majors and took an intro course in another subject and fell in love with it. Whatever your major is, it should be something you love and could see yourself having a career in.
The biggest mistake people make is listening to what other people tell them they should do. Someone's parent tells them they have to be a lawyer and they start failing classes because they just can't grasp the material or they just simply aren't passionate about becoming a lawyer. Being in a major that you are passionate about can help you become more enthusiastic about your classes and help boost your GPA.
Moral of the story here is this, changing your major after you've already chosen something is a big decision but it's not detrimental to your college career. It can give you options you never considered before and allow you to choose a career that works best for you and one that you love.
