First you need to sit down and figure out why your score was that bad. Was it driver irons, short game, putting? The older i get the more I sit down and realize where my scoring goes wrong, and the less of a gap I have between my good rounds and bad rounds. Know your tendancies!!! If your slicing your driver, don't hit it on holes with trouble on the right. If it's your putting is off that day, take a little extra time with your short game shots and concentrate on getting it closer to the hole. Whatever your problem is that day be honest with yourself and think your way around the course. You would be amazed how many strokes you can shave by using your head on those bad days. Jack Nicholas once said he has played some good golf with some bad swings, but he always knows what swing he has on that particular day and uses his head to get around the course with it.
