Coming to college there are expectations of knowing exactly what you want to do, and that is rarely the case. There are so many people that don't really know what they want to do, or people that change their minds half-way through a program. It shouldn't be taboo to change to a new major that interests that person more than the one they currently have. I have changed my major twice and I feel like I can finally enjoy the classes I'm taking, and feel like I can do something with this major.
Coming to college right from high school, where you need permission to go to the bathroom, and then needing to know exactly what you what to do with the rest of your life is unrealistic in some cases. Of course people come to college knowing exactly what they want to do and they stick with it. But, just because people change their minds doesn't mean they failed. General educations are meant to help students explore new subjects, even though we all hate them, they really are a great resource for students to see what else is out there.
I know more people that have changed their major, or have added one, than those that have stayed with what they have originally intended. Making mistakes and changing majors is a rarely basic part of college for most students. Starting off as a psychology major, I thought I would love doing the classes and everything, but that was far from the case. I didn't like what I was doing in the classes, and the material I was learning was boring to me after a while. I loved some of the material I was learning, but I knew I wouldn't enjoy the the major as I whole. I changed to English Education, and I loved my classes. I thought it was something I would do the rest of my college career. But, I loved politics and loved to learn about law. So I changed to political science and I don't think I could have made a better choice.
I love my major, my classes, and everything that comes with it. I know my family was going crazy when I wasn't sure what I wanted to do, but they feel this is the path I was meant to be on. Other people that change majors shouldn't need to worry about what other people think, because it is their career at the end of the day. If they love it, let them go for it without remarks such as "why are you changing your major" "are you sure you want to do that?" and so on.
Sometimes making a change is the best decision you can make. Trust in yourself and do what you feel you will love at the end of college.
