I seem to be having a mental block or choking issue. I am really happy with my game right now, but i have a high percentage loss on hill/hill matches and the last 2 weekends im battling for 3rd and am up 6-3 races to 7 and just cant finish it and have many chances, i make more errors in those final 2 games than the whole tournament. I start thinking things like( ok you can do this) (ok you have a great chance at it here) and i start feeling things like my heart throbbing and my hands feel like they are shaking but they arnt, and i think it affects my decision making, or at least makes me feel in a rush and dont look at all my options. So im looking for some advise or an article or book so i can work on this issue because it appears its not going away, any help is appreciated thanks!
