Make sure you write regularly

Having told you not necessarily to publish everything in a traditional manner, I would recommend that you start trying to write regularly. This could be typing up experimental methods and results so that they are ready as soon as the decision to publish is made, putting together review articles or free-writing around a research idea.
This writing will hopefully improve your productivity, as well as helping to organize your thoughts and create new ideas, as well as potentially helping you overcome any stalling points in your research. It might be that you are trying to develop a total synthesis and you are stuck on a single step, by searching the literature and making notes on what others attempting similar transformations have done. This is likely something you are already doing, but by keeping written notes you will be have something that could potentially be the basis of a review article and you may notice connections that you wouldn’t spot if you just read and highlighted articles.
Finally, practice makes perfect and by writing more your communication skills should improve.

Might checklists improve your manuscript?

I started off as an editor, editing manuscripts to house style, as well as copy editing them to some degree to hopefully improve their readability. Each time I saw a document I would have to check for different aspects of style or language. Often this was not the most exciting thing to do, especially when I had seen the document previously. To ensure that crucial steps were not missed we had a series of checklists that could be used enabling you to tick of each task as it was done.

These checklists were not prescriptive with hundreds of elements, rather they had a few elements (typically up to 10) with the emphasis on steps that were often missed or left incomplete. For example when proof reading a manuscript the checklist items included:

  1. Check that all references are mentioned in the text
  2. Check that all tables and figures are referenced appropriately in the text
  3. Double check the title for typos

The title was included on the list because it is often difficult to spot a typo when you know what should be there, it is a short piece of text and it is often very large.

This use of checklists is discussed extremely well in The Checklist Manifesto: How To Get Things Right and I highly recommend that you read it.
