If there was one thing I could tell my senior year self, it would be that I didn't have to rush into choosing a major. Sure, it is one of the biggest decisions one makes that paves the path to their future, but it shouldn't be rushed. Making a choice like this isn't as simple as choosing what you would like to eat for lunch, so it should be considered for some time. Why would you want to rush into a decision that is going to have a HUGE impact on the rest of your life?
Whatever you do, don't think you must go into college with a set plan of the rest of your life. It is absolutely unnecessary, and causes more stress than it's worth. If you know, that's awesome! You are a part of the very small demographic of college kids who have their lives semi-figured out. However, if you don't, don't sweat it. There are so many students like you that are also trying to find their paths.
As you meet new people and experience a different kind of class style, you may find that what you thought you wanted to do is actually far from what you now see for yourself. Instances like this happen often, and it is best to be open to them. Don't try to tune them out, you may wish you had listened. If you feel like you may be changing your mind, talk to a counselor. I wish I had gone to see mine way before I did, and now I try to go as often as I can. They're a really great resource, and they can hep you sort out whats going on in your head. Be open to what you may find yourself enjoying.
Overall, choose to pursue something that is going to make you happy. Even if you don't know what that is right away, keep pushing. You will find yourself on the path that is right for you, I promise.
