It is my suggestion that when you are editing your photos for the first time to never go back and look at the photos you did not select a second time. When you do so you will come up with excuses as to why a photo is strong - which usually relies too heavily on technical hoo-haas versus the photo moving you on a gut level.
If, however, you are to go back and look for photos that you feel you may have missed. Then do so with a specific goal in mind. And I suggest, for you to write it down and commit to it before you start.
For example, if you need more portraits, look only for portraits. If you need more close-ups. Look only for close-ups. Do not go in there and just wander around. That would be like wandering into your closet trying to figure out what to wear and doing nothing but wasting time because you have not chosen a specific occasion or activity to guide what type of clothing you should be selecting.
When I didn't have this guideline for myself, I'd often go back and look through all my photos dozens of times, combing through all my photos to make sure I don't miss a single shot. But this is very time consuming, and when push comes to shove, I just end up choosing the original photos I chose during my first round of edits. So, don't make the same mistakes I've made.
