Great topic!
My club has players of all skill, focus, pace, anger, cheaters, rules know it alls, and guys just out to have fun, so you never know who you might get paired with. I have found the less I care about what anyone else is doing the more I enjoy my rounds. I used to play competition and would be bummed when I played bad, or got paired with a jerk, or with the guy who really didn't care that he was shooting 90 and shouldn't have even entered the tournament, and I realized I never stopped to enjoy some of the great courses I was playing and some of the great shots I was hitting.
About 10 years ago I just stopped caring about what my scorecard said at the end of the day, and I just tried to hit the best shot I could at each opportunity. I am competitive, and I love to gamble on the course, but I don't take anything with me once the round is over. One of my best friends, and frequent partners is extremely focused on the course, doesn't talk to our opponents, ever, and seems like a total DB. It def gets under the skin of our competition and he knows it. We play against guys just like him all the time, and I just chuckle because they just end up trying to out DB each other, and I usually coast along and end up with the best score.
Golf is fun, competition is what makes it great, and the beauty of being outside is you can simply walk away from the DB's and enjoy the views all to yourself. Focus on your own game, and relish in the fact that you could be stuck working!
