Section 3 of my manuscript is due this Wednesday and after continuing my research and writing, I am starting to wonder how I will write the conclusion. My worry is that I will have nothing productive to add to the literature that is already out there. I do not want to go through all this work and have accomplished nothing. I keep reminding myself that this is the first review I am writing and I will improve tremendously with practice. Time will tell if my work will be seen as productive in the scientific community.
