my last few rounds i have been playing well, but i begin to become to focused on my score. for instance, i had this theory for a while that if i was 1 over every 3 holes then id shoot 78. nothing real special but i'd be happy with it. ill start of real well and shoot 1 or 2 over on the front nine and then get too focused on my score and shoot 40 on the back. I'm sick and tired of blowing up at the end of my rounds. are there any strategies or tips to overcome this?
