Tee up your ball within the tee box strategically, depending on the shot you intend, or are likely, to hit. Don’t just tee it up in the middle of the tee box… straighten out the hole as much as you can by teeing up on one side or the other.
Why it works:
You can alter the angle of a dogleg-right hole in your favor by teeing the ball up on the left side of the tee box (vice versa for a dogleg-left hole). Think of it like in billiards, when you place the cue ball to your best advantage after your opponent scratches. Sometimes the tee box isn’t level everywhere, and you surely don’t want to be standing in a hole for your tee shot. Or sometimes you want to favor the right or left side of the fairway due to the wind, or because you are playing a fade or a draw, or because you are not using your driver, or because out-of-bounds runs along one side of the fairway**, or whatever.
No matter what the particulars, pick your teeing spot and your aiming point carefully and deliberately and you will get better results, more often.
