Will University Writing Classes Melt Your Creative Brain?

I don't know.  I am currently a creative writing major and I am loving class and the teachers but the text books?  Why so much flippin' structure?!  I love to just write without thinking about whether I supported a good thesis statement with a quality question that will entice readers.   Yes that is important, but my brain works on a much different level and the only question I would ask myself is "would I like to read this and do I find it interesting?"  I understand there has to be structure to writing but who's to say mine is better or worse than yours?  Isn't all that matters in the end that people will read it and enjoy it?  I fear I am going to have to walk a fine line of doing the work and not getting worked over.  Let me know what you think.  I am curious to hear from people who have taken classes and people who just write.
