If your anchor point is on the top of your head and it's "comfortable" for you then don't let others tell you you are anchoring wrong. I've had numerous ppl try and tell me that my anchor point is wrong, that the string should be at the tip of my nose and not along side it, and the fletching "shouldn't" be in the corner of my mouth. Granted these ppl giving the suggestions may have been shooting longer than I have, as most of the ppl on this forum probably have. And I'm pretty sure they all have the best of intetions in mind.

My point is this, shoot from where you are "comfortable", and relaxed with a possitive attitude. And JUST listen to others advice then decide if it's "comfortable" for you, if not discard it and you'll stay in good shape. And the "bad" habits you form will be your own and not what someone else has helped you put there.
