Since you have the planet Mercury ruling your sign, you need to always be communicating. You may have been talking much earlier than other kids, and exhibiting a natural curiosity about the world around you from a very young age.
These days, you may continue this need to communicate by writing a blog, planning the next Great American Novel, or giving speeches on topics that mean a lot to you.
And you don't just talk. You're in the action, too. Getting involved in causes, from preventing heart disease to making sure animals get treated well, helps put your message into the world.
