FIGHTING AGAINST BOREDOM If we go through the history of any field of science, there have been always many unseen, intentionally neglected, or ambiguous facts. New generation of researchers, push the borders by addressing these gaps. As time passes, these dark spots get finer and more difficult to detect. In my way to PhD, investigating these missing parts of the science puzzle is the most challenging struggle. It is challenging because not only these parts are less likely to show up, but the process of digging the literature can become long-lasting and boring as well. If I pull myself through this stage, I would surely be self-motivated and thrilled enough to wrap up my PhD journey.
