I have no idea what I want to do for the rest of my life. Hell, last year I was 18 and raising my hand to ask to use the bathroom. Should I know what I should be doing for the rest of my life? That sounds like a pretty grown up question that I don't know the answer to.
When I came into my first year of college I was declared in political science; I was declared in political science because my mother thought that I would be a good lawyer due to my fondness for arguing. Word of advice -- do not go into a major because your mom thinks you would be good at it, rather than actually having an interest in said major. I hated political science; not because it was a crappy major, but because I didn't really understand it, and I wasn't interested in it. Within the first three days I went from being declared, to not knowing what I was doing with my life -- and I was having a meltdown because I thought I was wasting 25 grand on going to school because I didn't have a path and was newly undeclared.
Being undeclared is unheard of in college. Freshmen usually know exactly what path they are going to be walking down for the next four to five years. I, however, was not one of those freshmen, and I was terrified. What if I don't find a major that I like? What happens if I'm undeclared for more than a year? How am I supposed to finish college in four years if I was undeclared for a quarter of that? These were the top three questions I was asking myself and my advisor. My advisor was actually an angel in disguise, because she really reassured to me that sometimes people don't even work in the area that they studied in; prime example was herself, she graduated with a degree in environmental science and is now a full time advisor.
Undeclared is the best path to go. I think that it should be required for every first-year student for at least a year. Being undeclared doesn't mean that you don't take classes that can help satisfy a major; it means that you take classes that might be able to satisfy an array of majors. That way you are able to really take a look at a bigger range of majors instead of going into tunnel vision by going into a major and just sticking with it because that is all you know.
Your undeclared advisor is super helpful, and knows almost everything there is to know about finding your own way, which usually consists of taking classes that satisfy your prerequisite courses but also help you see what each major is like. Being undeclared is also nice even when you know what major you do want to go into, mainly because you are able to still take courses you would be able to take when you are declared, but you are also able to take courses that are just fun to take.
Being undeclared is okay! Start with a minor, or two, and work your way up to figuring out what you want your major to be -- like I did. Have fun, figure out what you really want to do with your life, because after college you will most likely be doing something in that field for the rest of your life -- scary right? It gets better, trust me.
