How to Tee-Off without getting Teed-Off
The take away is super important because how you take the club away largely determines how consistent your ball striking will be.
You see, the consistency of your ball striking will only be as good as the downswing moves you make to get to impact. And the downswing moves you make to get to impact will only be as good as the transition moves you make. The transition you make will only be as good as your backswing, and your backswing will only be as good as your takeaway.
"The old maxim that the entire swing is governed by it's first few inches is certainly true in my case. I can sometimes instinctively make midswing compensations to produce an effective shot after a poor start but, generally, when I start back incorrectly I hit a mediocre shot."
Jack Nicklaus
And as Jack Nicklaus is quoted above, you can make compensations in your swing to hit the ball OK but you'll be a better, more consistent golfer without forcing yourself to make in swing compensations if your take away is correct.
Sadly though, I see so many golfers taking the club away incorrectly, and by incorrectly what I really mean is with their hands. Instead of sweeping the club away with a one piece takeaway, most golfers pick it up with their hands. Doing this leads to all sorts of problems later in the swing and makes the golf swing a lot harder than it needs to be.
That's why I teach my online students to work hard on perfecting a one-piece take away that is on plane, because that's the easiest and simplest way to start the swing -- and that makes the rest of the swing so much easier.
What is a one-piece take away?...you may be thinking.
Well, when you're setup to a ball your shoulders and arms should form a slightly imperfect triangle like this:

Important Note: This triangle that is setup at address should remain intact until your left hand is directly over your right leg. Because at that point the take away is complete.
When you have completed the take away the club has only moved 3 - 4 feet but it's crucial that you get this part of the golf swing correct because it will make your golf swing a lot simpler and easier to repeat consistently.
That's the one piece action covered but that's not all there is to the take away, because when you take the club away from the ball you need to make sure it moves on an arc just inside the target line, NOT straight back along the target line.
Because a straight back take away gets the club traveling too much outside and causes your arms to become separated from the body. All of this will require compensations later in the golf swing which will result in inconsistent ball striking.
So you need to perfect the one-piece take away while taking the club away on the correct path.
