When we talk about the concept of positive thinking, we refer also to our emotions. As stress and anxiety are closely #connected and influence each other, that happens also with our emotions and thoughts also. For example, Predoiu in 2016 said that between emotions and thoughts it is a direct link (our #emotions shape our #thoughts), and for that, we can presume that has a #positive or negative effect on sports #performance. http://humanperformancepsychology.com/2019/07/01/positive-thinking-and-sports-performance/
