What a great response post. I think it’s pretty cool that you took that extra time and care with your work to figure that out. And, I suspect, that even though you didn’t use every detail of what you researched, it still found different ways to show up in the work (in subtext, background and general confidence from you as the writer).
As for finding it a bit timing to meet deadlines, I’d suggest striking the balance and figuring out what you need most and when. Some things need more research than others, and sometimes you have more time to do the research than you might at another time. Find the balance and keep practicing. You’ve got this :)
