The complete sentence goes:
"This is not a perfunctory guideline. (...) This is something you need to pay close attention to while you code."
Something in "to pay close attention to" is bugging me. Any suggestions on how I could improve it? Or does it sound ok as it is?
Edit: there have been some suggestions to use "focus on", which should work in most cases; however, in this particular case, I'm not saying that it should be the center of one's attention, rather something very important that needs to be checked constantly.
