A lot of players don't take the care they should about aiming, especially from the tee. Instead of looking out at the fairway and thinking anywhere out there is fine, you need to have more of a plan, and more of an aiming point.
I like to start by picking a landmark on the horizon that's on the line I want my ball to travel. In this picture, I want to take my tee shot off the right edge of the hotel, with a little draw.
Once I pick that landmark, I find a spot on the tee or in the fairway a few yards ahead of my ball, on the same line. That way, I've got a much closer frame of reference when I actually set up over the ball. It works the same as those little diamonds on the bowling alley. You're trying to roll your ball over one of the diamonds, instead of aiming at the pins themselves. light.
