Mondays are a good day to make statements, not Friday.
Grip pressure - not mechanical flaws - is the biggest factor when you're nervous. You unconsciously grip it tighter, which keeps you from making a smooth swing with a natural release. Keep your grip pressure light, and you'll be surprised how much your mechanics stabilize.
Before you take your address, while you're still reading the putt, imagine the ball tracking on the line you've chosen and falling into the cup. If you don't believe you can make every putt, why bother trying?
For all the fun, don't forget: I always knew when to put my golf balls down and practice.
Because of the grass and open face, I take one more club for shots from the rough, unless the ball is sitting on top of dry grass. Then, I use more loft and swing softer, trying to hit it about 70 percent to avoid a flyer over the green.
From a good lie in the middle of a fairway bunker, I'll make the same swing as I do from an average fairway lie. I'll dig my feet in slightly and keep my lower body stable so I won't slip, but I don't change my club selection or setup. It's only when the ball is sitting down in the sand that I'll make some modifications.
