I had a whole summer of chocking where I lost like 16 matches in a row, some in a very spectacular chocking fashion (like a f*cked up 5 match-points in one of my matches). And I always felt bed during the match and after the match, so I stoped caring about the end result. And there were matches when I just didn't want to be on court, regardless of the opponent's level. Seeing that I started to read a lot of theory on mentality in tennis, but it was always hard to put it into practice.
And when I had a match that I knew I would never win. As a Nr 17 000-something in the country I played a top 200 player. And although I've lost 0:6 0:6, I also played the best tennis of my life, I had no inner restraints, I kick-served and sliced the second serve as I knew I could, and didn't serve my usual "100 % in 0 km/h" chicken-sh*t-serve, and so on, and I just memorised the way I've played.
Then another thing came to my mind: I spend money on coaches, I pay the club fee, I pay tournament money, I pay for stringing jobs, and if I can't play a good match and win, it means I just spend all that money for nothing. I was kinda furious at myself and decided that from now on I will play the best I can regardless of the result and I will just enjoy my game as I did in that match. It's still hard for to play in the present not thinking about the outcome, but I just decided to fight more, try to go for every ball and do what I can do best on court. I think now I've chocked mostly because I didn't enjoy being on court, and I probably subconsciously never wanted to win too (for many reasons, including empathy). It is kind a banality, but it really helped me. In my last tournament last week I've made it to the final for the first time in my life (although there were only 4 rounds) really just thinking that I have to enjoy my strokes, my movements and my tactical decisions and that I don't have to care for lost points.
