That's one of the interesting things about golf, isn't it - that every one who plays the game long enough and seriously enough has to learn let go of "what might have been" and to move on to the next shot or next hole or next round with as much equanimity as possible. So, ironically, that means that at some point we might develop an attitude that actually gets us less out of a round (i.e. we score worse) than we might have -- since we're not asking ourselves what might've been anymore, we play the same hole (and similar holes) the same way again and again. John, you tried to drive the green 3 times on the Par 4 #10, got there once and got close twice, and ended up with a par each time. Maybe a player who's worse than you should be happy with that; but I'm surprised you didn't try to play that hole any differently, and surprised that you're not wondering if you might've birdied #10 once or twice if you had played it differently.
