Smiling during competition and refocusing after errors

Australian footballer (soccer player) Archie Thompson makes a very insightful statement about enjoying himself in the moment while playing and refocusing immediately after making errors. Beating yourself up for a mistake is just wasted time when you can instantly get back to reaching your highest potential in your craft. Thompson, who once scored 13 goals in a game, notes this in his book entitled What Doesn't Kill You Makes You Stronger:

Jon Jones is a fighter who sometimes will showcase a smile to savor in the sport he loves and also because he feels he has done his absolute best in training. Additionally, Alex Caceres (AKA Bruce Leeroy) plants a big smile on himself to enjoy himself the most he can enter into combat and also to minimize stress levels on his body. In terms of being in the moment, former Bellator champion and top lightweight contender in the world, Eddie Alvarez, is someone who tries to empty his mind and react only to what is in the "now". He isn't worrying about what's going to happen one minute from now, or what happened one minute before, but completely immersed in the present moment.
