Don't give up yet. I had exactly the same problem. My problem was without even knowing I was putting more pressure on myself to play better around good ol dad. This kept me from staying focused entirely on the present.My State appointed therapist said to speek to myself and explain what exactly I wanted to do with each shot as I scoped it out.(As if I was hosting "Playing Lessons from the Pro's") This has worked wonders for my game.I'm talking ten strokes off my handicap since 80 to 90 percent of my rounds are with good ole dad

Then again maybe I'm just crazy.
