Everyone has their vice. Everyone is comfortable doing what they always do, and things that they really like to do. There are people however that have a lot of things they like to do, but have no idea what they want to do in the future. Everyone goes through that at some point, but some people grow out of that stage very quickly. It's okay to get out of that stage, and it's okay to remain in it for as long as you need.
But my advice for you is: when you're in college, don't just take the classes you know you'll like. Get out there and try new things. But please, at least take one communications course.
Now this might just be because I am biased, and I am a Communications major myself, but those classes will truly help you in the long run.
Do you have a hard time doing public speaking? No problem! Take a Communications class and you'll have no choice but to get over that fear! Many professors in that field realize that a lot of the students take the courses to fill a social science requirement for general education classes. But what they want to do is make it fun for you, while still sticking to the curriculum. Take a simple intro course. For that you'll learn the basics behind every means of communication like interpersonal, organizational, intrapersonal, etc, and be able to put them to the test in different forms of speech like informational or persuasive. In these instances you often get to pick what you will be speaking about and you get to do it in a room full of nonjudgmental Communications major who have to do it for their major.
So not only do you get to do it on what you pick, but you get to work with students who are going through the same thing. Plus these speeches will help you overcome your fear of public speaking!
If you're undecided, you could fall in love with it and stick with it for a career. When I took my first Communications class I had no idea what I was getting myself into. I took a course on media literacy. I had no idea what that was, or why I was going to be there. But during the class we took days off of using any technology, analyzed music videos and commercials for underlying meanings and what advertising companies will do to secure revenue. I have never felt more in my element and I never used to be interested in that sort of thing. I guess I have been inside, and never put it to the test.
You will learn things about yourself that you never knew. I'm sure that if you stick with it, you'll eventually need to take a theory and research class. The theories that are portrayed and researched in Communications are remarkable. You'll realize that a part of you is in every theory, from Rhetoric, to Genderlects, and to Cognitive Dissonance. These theories really open up your mind to what you have done in the past, and what is happening in your present life and what you can do about it.
This isn't trying to convince you to take a Communications class, (just kidding, I am trying to do that), but to get you to open up your options and take all sorts of different classes and put yourself in out-of-your-ordinary and out of your comfort zone to try new things and find new vices. I hope you enjoyed this and take a leap of faith when scheduling your next semesters classes!
