I never hit a shot, not even in practice, without having a very sharp, in-focus picture of it in my head. It's like a color movie. First I 'see' where I want it to finish, nice and white and sitting up high on the bright green grass. Then the scene quickly changes and I 'see' the ball going there: its path, trajectory, and shape, even its behavior on landing. Then there is this sort of fadeout, and the next scene shows me making the kind of swing that will turn the previous images to reality.

I've never set up any golf course that would favor anybody. I try to make it exactly the opposite, which is what we did at Valhalla when we modernized it to accommodate the lengths players are hitting it today.

Nobody - but nobody - has ever become really proficient at golf without practice, without doing a lot of thinking and then hitting a lot of shots. It isn't so much a lack of talent; it's a lack of being able to repeat good shots consistently that frustrates most players. And the only answer to that is practice.

None of the guys did anything. We never did anything. I never really got into the workout room until I was about 40 years old. I was pretty strong and I didn't think I needed that much.

Keeping the head still is golf's one universal, unarguable fundamental.

Well, I think that Augusta is not the same golf course that I grew up on. Bobby Jones' philosophy was giving you space off the tee; if you put it in the right side of the fairway, you ended up getting the right angle to the green.

Every putt is different. Your feet dictate the stroke by how they feel on the green. I just never used the same stroke on every putt.
