Actually, I've tried storyboards and they have never worked or made me more organized. I'm not saying people shouldn't do them, I'm saying for me I have tried them a bunch of times and they didn't do it for me. I do have a script and from time to time I'll do storyboards, but only when it is necessary for complex stuff like pop-up books (I do my comic in my Sketchbook) fight scenes, shape shifting scenes, dream/drug scenes, etc. Concepts that are abstract. The other time, I'll just do what my brain wants to do as I daydream constantly, I talk to my characters and live in their world. So with storyboarding it just depends how complex the project is, and what I want. This is why so many of my drawings are dreamlike and experimental because I draw exactly what's in my head at that moment. I also use references and books and my script to guide me as well as character references. In other words, they are all automatic drawings. I don't think about color or composition as it's already there on the page, in my unconscious mind. Ernest Hemingway never did a script, he just wrote for that hour in the morning. Also, artists go through phases. Picasso went through his Blue period and never thought about yellow once. Maybe, I'll go through my yellow period and visually incorporate that into my comic as it is semi autobiographical. I don't see my comic as a comic, I see it more of a journal even if none of these characters are me. The script is loose for a reason and that's because the elements in the room and my emotions change things ever so slightly. My emotions might change a color scheme, or a poster that I really liked, I might sample some of it and somehow put it on the page, in clothes or in people's hair.
So, don't worry. I am not going up a river with one paddle. I see your concern and I do storyboard but only when it is needed. Because I see my comic as a journal, my storytelling works differently than most people's and I am aware others are going to criticize me for my bizarre methods. That's okay. I totally understand where you're coming from and I might pick up storyboarding again when I'm older.
