This is why I gave up photography as a hobby. I don't 'the eye' for it. All my photos come out bland and badly composed. These days my DSLRs and all their lenses just sit in a draw gathering dust.
Photography courses teach basic composition skills that you have to know -- that is, if you follow them blindly you'll get decent and non-boring photos -- and then you can develop your style by selectively subverting them. I suppose getting your own style is about breaking the rules to get more "interesting" and unique photos.
