Tips for revising manuscripts months later
Give working on the revision the highest priority within your research tasks. After all, this is the last step before getting your results published, so it's best to get that off your table as fast as possible!
As first step when you get the reviews, go through them carefully and note / mark every comment which you think requires you to revise something. Then, for each marked comment, make a plan how to address that point, and think about what a good sequence for working on the comments would be. For me it works better to first address the more large-scale points, but that may of course differ from one person to the other.
Deal with each comment one-by-one: make the required revision in the paper, and directly after (or maybe before) that write the corresponding response to the reviewer's comment in your response letter.


If you have a comment that raises issues with the overall flow of a section (for example something like "The introduction does not clearly lead to the problem that the author is dealing with."), it may be most efficient to rewrite that part from scratch instead of trying to revise it. Then you can also simply answer something like "The introduction was completely rewritten to address this point".
