The Goat symbolizes Capricorns, and an apt mascot it is. Goats love to climb to the top of the mountain, where the air is clear and fresh. In much the same way, Capricorns want to get to the top of their chosen field so that they can reap the benefits of success; namely fame, prestige and money. Getting to the top isn't always a walk in the park, however, so it's likely that Goats will ruffle a few feathers along the way. These folks can indeed be domineering, even egotistical, on their route to the top. They'll tell you it's part of being a leader with bright new ideas (in keeping with the Cardinal Quality assigned to this Sign).
Capricorns are industrious, efficient, organized and won't make a lot of waves. They are scrupulous with details and adopt a rather conventional posture in business and in life. These folks feel best playing it safe, since this is a fail-safe way to get to the top -- eventually.
Thankfully, Capricorns are patient, too, and are happy to wait for their ship to come in. The flip side to this staid behavior is that Goats can become quite unforgiving of those who aren't as diligent or ambitious as they are. Capricorns need to remember that they do need allies along the way, ambitious or otherwise. In any case, once Capricorns receive the recognition and social status they so fervently crave, it's likely that all will be forgiven.
