When you see a hawk what does it mean?

When I was 17 a hawk flew into my backyard, (this had never happened previously) landed on a unusual, hard to reach perch and looked me in the eye. This was the moment that I decided to change my major in college (more importantly, I was verbalizing this to my lifelong music teacher) from Jazz Studies to Economics - a very profound and life altering decision for me in my life (I am now in my late 20's and at the time was practicing 8 hrs a day). The next week my music teacher brought me lots of literature on Native American animal symbolism, all of which pointed to one conclusion - this decision was an important one. It took me most of the next decade to understand what that day meant but I now believe that hawks (a bird with amazing VISION and PERSPECTIVE) appear to help you realize that an important, and to me, highly intelligent (and perhaps clairvoyant) decision has been made. . .
