For me, something good happened today is that I successfully submitted a manuscript to a journal this afternoon. The submission of the manuscript stands for a good progress of my recent research work. I am a research student so I need to read new articles in my field day to day and come up with new ideas to fill the gap. There are many limitations of the current research. For instance, researchers may make many unrealistic assumptions to reach a closed results. My job is to find their limitations and to make their work more realistic and practical for the industry. It is boring but with fun if you can enjoy the process. In fact, many works in the world are repetitive but for me, research work is creative and will change the world finally.
