Yep--those shots in the past are just that--in the past. I've bugger myself in tournaments by thinking about a shot I messed up on, which caused me to not focus on the ones coming up, resulting in several buggered shots instead of just one.

Pick a spot, burn a hole in it mentally. Aim for the spot you want the arrow to exit. Stay within your comfort zone, and even then if the shot doesn't feel right, don't take it. You can get the job done.
