No! Not bad at all! Students do it all the time!
A lot of times students go into college thinking "this is what I want to do" and then find out that's not it at all. Or, maybe they take a class that ends up sparking an interest in something they didn't know existed, got involved in a student group that inspired a committment to a cause, etc.
If you'd need to change your major, go straight to your college academic advisor and talk about the ways you can redistribute your existing credits into a new major. Or, consider adding a minor.
Today's work world is what is called a "gig" economy. People change jobs all the time. It's ok to expect your interests to change, it allows you to build more skills.
As far as making decisions about what careers might be a good fit for you, I suggest you take a look at O*Net. It's information from the department of labor. It gives tons of great information about careers/jobs including what skills are needed, education, what the tasks look like, how much they make, and is it a growing field in the next 10 years, etc.
Make use of your college's career center. They can help you clarify your goals, point you to opportunities for internships in fields you're considering, and review/advise on your resume and cover letter. The Career Center is designed to help ALL students, not just seniors. The sooner you go the better.
