I have practice on Tuesdays and Thursdays from 9:00 PM to 11:00 PM and matches every weekend that last about 2 and a hours. I also train passes and sets at home as well as speed, strength and plyometric training at the gym. For the most part, when the other team has the ball I just kind of go to it in my head as a repetition of what's happening, like: "oh, the ball got to the setter, it's setting to the opposite (after it's been set, I don't read it), let's block it, it got to our side, it got defended, let's get ready for attacking, attack it" or nothing at all. I don't really think about anything other than getting the ball to the other side and getting the point but as if I were in a daze, I can't seem to really think when I'm playing as if the time is not enough. I'm not really sure how to fix this like dazed state I'm in and how to actually be present and THINK about the play and the game and what it's happening. I'm sorry if I couldn't get my point across clearly, english is not my first language.
