Everyone wants to improve. No one wants to lose. The hardest part to accept about both of these statements is that you cannot improve without losing–it is fundamental to the learning process of fighting games to encounter a problem and figure out a solution.
YouTuber and top British player King Jae suffered a big loss recently in top 32 at Tattakai Holland. He took this loss not as something to fret over, but as a learning (and teaching!) opportunity for himself and his audience. In this video he shows you how he re-watches his matches, and what he mentally takes notes on to help improve his game for the future.
