Stan I too had a father who did not accept that something could not be done. With enough leverage, effort or planning whatever needed to be done simply had to get done. And he was right. I came to understand all the mental effort to find reasons to fail would be better spent trying to find that peice of pipe so I could get the job done. Amazing what lessons dads can teach sons sometimes.
About keeping scores, many years ago I had a fellow club member who was always trying to beat me at everything. One shoot I had a hundred and he had that bridesmaid 99. While drinking a few beers later he proclaimed that it was only a matter of time before he'd be beating me to which I replied that I never kept score when I shot? Do you I asked? Yes he did he said and asked why I did not. You can not break 100 you can only break one at a time so your only score to worry about is a one or two. Be perfect on each shot. I said that when you hit them all you don't have to keep score because the best others could do is tie you not beat you and I intended to break them all and as long as I broke them all he'd never beat me. I could beat myself but no one else could. He laughed but did not understand. In the next six shoots I broke 598x600 and he never ended up beating me, others did. He soon lost interest and went on to golf. But it is the same in golf, one shot at a time. Thanks dad, my dad kept score and now I know why so that I would do it his way
