You can't swing with hesitation; you can't try to steer the ball to the flag; you can't worry about that water hazard as you take the club back. You have to pick the right club, visualize the shot you want to hit, and then focus on that shot until the ball is gone.
To flight approach shots lower with the scoring clubs - what I consider my 7-iron through wedges - I stand two or three inches closer to the ball than normal.
The beauty is, while you're working on chipping, you're also working on driving. This is because the bottoms of both swings - the area around impact - are identical.
It's very difficult to consistently hit good iron shots if you get off to a bad start. That's why I'm always paying attention to my setup and takeaway.
Most amateurs are so worried about mis-hitting the shot or hitting it off line, they don't make an aggressive move. You'd be surprised how much better your swing will get if you let your natural athletic ability shine. So go after it.
People look at me weird because I'm a Howard Stern fan, but he's very misunderstood. It's the first thing I do when I get in my car at a tournament - just pray that I get Howard 100 on Sirius or XM.
It's such an advantage to be able to hit short irons low on command. When it's windy, you'll hit more greens. But low shots are a great strategy in calm conditions, too: The less time the ball hangs in the air, the less time it has to stray off line from the flagstick.
