I would like for my story to continue moving, but I find that I interrupt action with details or inner thoughts, mood, emotion, etc. Hence, how can I spot an interruption in my writing that could drag the quality of my writing down?

Furthermore, I have tried to dedicate a paragraph or a large a section to focus on specific things such as description of setting, description of select items, inner thoughts, action, etc. However, I find that it is **too much** all at once. So, how can I structure my paragraphs to allow the reader to focus on one specific idea, and keep the story moving without piling on too much of one idea?
