"You try not to (think of the negatives). I think that's what all golfers do, we rationalise everything. You hit a bad shot, it's not that bad. You should always try and look at the glass as half full. There's always a bright side to everything, you've just got to find it sometimes." - Tiger Woods after dismal putting at the Players, yesterday.
And therein lies the issue. Finding it. Identifying it. And most importantly, it being enough. It never usually is. And this is not just pessimism. Its pretty realistic.
I would write more. But I'm still recovering.
