Choose the journal where you will submit your piece before writing it and peruse the submission guidelines attentively. Otherwise, you will have so much revision to do, you will be bogged down in it forever.
I just made the mistake of deciding what journal to submit to (which was decided with the kind help of my colleague Jonathan) after the piece was ready. And then it turned out that they accept 20 pages maximum. I cut down the article as much as I possibly could but I still have 21 pages with bibliography.
Also, if you think you might decide to publish overseas, then remember that you will have to overhaul the bibliography and the citation format completely. British journals, for example, have a completely different standards for the bibliography than American journals.
So choose the journal and only then start writing.
P.S. Probably everybody already knows it and I’m just inventing the wheel, as usual.
