WHAT'S YOUR ACHILLES HEEL? Achilles was a mythological Greek warrior, who was supposed to be indestructible except for one tiny spot on his heel. And thats the spot that destroyed him. We refer to these area as our "blind spots." Our blind spots are in the area of our weaknesses. Ego can blind us to our own vulnerability. If you're unwilling to acknowledge that you've got a problem, you won't protect yourself in that area or work on it, and as a result you'll keep getting into trouble. As a result of it we miss a lot of great things we could have had.
