Back in a day, I was a representative of my institute for resident paper contest at Orthopaedic annual meeting. It was my first time that I had to present the project in English in front of 500 audiences including invited big-name international speakers and the expert judges. It was an unforgettable event in my life, not only the presentation but also every process of project management especially the pre-contest research camping which was very intensive and stressful. I kept practicing hundreds of times, days and nights, by myself, with my friends and research team and in front of daily morning conference. I did my best and finished with first runner-up. The first time is always the hardest. As an introvert person, that was such a huge step. I had an opportunity to present this project again in Switzerland, a bigger international conference but with less stress and more relax on the stage.
