Here are some of my learnings that you might find useful to reduce stress that comes with publishing. To draw an analogy, I think starting a startup company and the PhD publication process have a few things in common. Both have an uncertain future initially, but both could result in a novel contribution in their respective areas in the end. Just like a startup, your publication process needs a survey, vision, strategy, iterations, and scaling. My thoughts are organized below in the same sequence.

All the sections of the Introduction should be balanced, thus you should reserve the same number of paragraphs to all of them, more or less. Up to now, you have written a draft of the abstract and the Introduction and Related Work Sections. You are ready to give a structure to your paper. I strongly encourage you to take again the Introduction and split it into paragraphs. Then, you could add one section for each paragraph. Remind that while writing the paper, you can add, delete or modify any section you have already written.
