A good way of looking at it is to just aim for par on each hole. Whether that means taking the defensive approach and hitting 3-wood, then so be it. Occasionally a birdie might drop, but then occasionally you might 3-putt. Just concentrate on hitting the fairways and greens. Don't be so concerned about lack of birdies and eagles. Just hit for the middle of the greens and make your par. As I said, every so often, you might hole the birdie putt which is a bonus. As for double-bogeys, being in single-figures like yourself, I try to avoid these as much as possible. I find that my round flows a lot more if I don't make a double and all my best round never have double bogeys in them. If you don't get overly aggressive and aim away from the tough pins, you will find the number of doubles you make decrease. Hope this new way of thinking helps.
