I once played a very good game against a German vice champion. Afterwards, people came up to compliment me, and the one thing they kept repeating was that I was smiling the entire time. I guess I was just enjoying myself. Most of the time, I forgot to do that, so I decided to make smiling part of my routine. It feels a bit forced at first. But by the end of the day, I’m genuinely smiling, having a good time, and feeling far more relaxed than when I’m only focused on the game.
