No offense intended, because you are a much better golf than I am, but I think this is terrible advice for tournament play. Playing for "bogey or better" (or any score for that matter) is a surefire way to put up a lot of bogeys, and it won't ever eliminate the blowups. I will grant you that on a tough hole with lots of trouble, I don't mind making a more conservative approach and being happy with a bogey result. But I don't ever think taking the mindset of "don't make worse than bogey" to a course will lead to favorable results.
I think ya'll may be taking @Pretzel's comment the wrong way. I'm sure at his level he wants to make as many birdies and eagles as he can, but if "bogey" is his bad hole it doesn't kill his round.
If you read about the rounds people on this site post the one thing that stands out like a sore thumb is that the higher handicap players can play along halfway decently and then start throwing up 8s about every other hole.
Limit your bad holes to bogey and forget about it and move on to the next. You will probably make up for it down the line.
Start that snowman snowball rolling and the round is shot. The more you try to make up for it the worse you fall apart.
