I love playing the game because it's an outdoor adventure. I might shoot the same score 2 or 3 times in row, but how I arrived at those same scores were not the same. I just like doing stuff out of doors. The idea of smacking a little ball around makes being out of doors eeven better.
As for the OP's three most important things he has learned, I would tend to agree with them......For the most part. Especially #3.
I don't know much about it, but if their captain chooses against somebody because that somebody is cocky or an "ahole" then their captain is stupid.
Making the safe pick who everybody likes is how you get crap like Jim Furyk on your team. Who wants a team full of nice losers?
Like I said, I don't really know much about it but for their sake, if they choose against him, I sure hope it's not because of him being overconfident.
Mine is 12.5%. I have 184 GIR and 23 birdies this year. Maybe one or two of those is a putt from the fringe or a chip in, but that's close enough estimate for me. If you include eagles, it goes to 13%.
