Was I just wasting my time in this class?

I’m in college.Before going to college and when I was in high school, I was thinking of majoring in journalism especially since i wanted to be on television involving news reporting and speaking forcertainrograms.Right now I’m doing basic classes, one of my classes is Public Speaking and right now I’m thinking of changing my major to Communications. I really want to involve myself in television and talk/be a spokesperson and that includes things like MTV,VH1,etc like Lala Vasquez.I kinda felt I really wasted my time in Public Speaking and not to sound stupid but can Communications involve with Public Speaking too?

A few days ago in one of my basic classes, one of my teachers were showing me and the students about registering for classes for the winter semester,one of the guest showed me how to it and what classes to take.When I told her journalism,certain classes was fine for me execpt one that involved politics(which I really dislike and don’t know a lot about).Too, Im reconsidering journalism since someone told me it’s mostly going to involve writing,newsreporting are falling rapidly into unemployment,and that journalism isn’t really what I expected.

I just want a successful career that I’ll be happy with and be well paid for.P.S. which career makes more money and tell me some facts about journalism and communications.
