Mental part of golf

What are some tips to help stay focused in a round of golf and how to handle the pressure of a golf tournament??

Good question. I personally like to walk the entire tournament.  I use the old clicgear, but I walk nonetheless.  This gives me time to think about what just happened, what is about to happen, and what the heck should happen. Since I have started walking, I feel so much more calmness throughout the entire tournament.  Not saying it's for everyone, but worth giving a shot!!
