Sekiro: Shadows Die Twice (topic now 200% easier to find)

My main problem with the game so far is: I cannot stay cool. I will always get so nervous that I do stupid mistakes. Stage-fright or something like this? I am still trying to beat the Seven Spears mini-boss. Yesterday was the breakthrough, 90% Mikiri Counter-success rate. I had him at orange/red posture bar for the last five attempts - then I had to go bed because of an important appointment today. Coming home I was thinking “yeah, max. 30min.”. Now it’s an hour. Two or three times I was sure that was it but… I got so nervous I did the stupidest thing. Mainly panic-jumping. Last five fights 50% of the Mikri Counter went wrong. I am losing it. I need a break. But, oh my, why do I get so nervous? It’s a stupid computer game!!! Grrr ;) Much to learn…
