I'm the girl who changed her major 5 times throughout the spam of two years so trust me when I say it takes time. Sure, some people know what they want to be before they even enter college and they end up doing exactly that, but some of us don't. When I left high school, I swore I was going to be a famous pop star or theatre major by now but that didn't happen.
Things change a lot after high school, it has been two years for me since I've been in high school and I can tell you right now I'm a completely different person. I've grown throughout the years and a lot of my thoughts about the world have changed too. I used to believe I would be a marine biologist saving the world and stopping overfishing but instead I decided I would help children with speech problems. I'm still helping the world, just not in the way that I thought I would be.
It's crazy how much things change and how your thoughts and views on career paths change as well. I did go through multiple changes in majors but once I found the major I wanted, I knew right away that it was for me. If you are interested in the material that you're studying and enjoy talking about it, then odds are you've picked the right major.
If you're extremely passionate about it and feel overwhelmed by the love you have for your future career path, then you're on the right track.
Of course, there will be days where you'll probably not love it as much as you do on other days but that's just a part of life. Every career choice is going to be hard but if you love it, it's going to be worth it.
