Interesting. I don't enjoy the concept of winning vs. losing. So, in the competition itself. Why should I worry about an opponent? It's similar in real life: I'd rather live every single day as if it were my last, instead of giving myself up and waking up with another chance. Maybe I just misunderstand you, or maybe your method doesn't suit me well... If it gets you further: go for it!
At a certain point in my sports journey, I became disenchanted with the concept of winner and loser. I stopped enjoying sports, and it simply became my job, which I no longer liked.
But what I wrote is not entirely about this concept. I will now attempt to explain it through a sports example.
A person arrives at international competitions that are very important to them. There are many participants, and based on the tournament table, they are faced with the favorite of this tournament—a very strong opponent. In the arena with several thousand people, the spotlight is focused on the future match area.
This person experiences strong excitement, and perhaps even fear, which restricts them and prevents them from unleashing their potential. I have seen many athletes for whom this hindered their ability to showcase what they are truly capable of.
This method is more aimed at combating the fear. It doesn't matter whether you win or lose at the tournament, but perhaps you can conquer the fear itself.
