I used to have the odd bad hole which usually started with a bad drive to the right. The best thing to do is keep calm after a bad drive and make sure you put yourself in good position for your third shot. A chip out sideways onto the fairway is sometimes the best option.

Another thing I try to do is "Try 100% on every shot"

It's hard to do when your having a nightmare but it's really disapointing when I know I didn't give a shot enough thought.
