Danger doesn't have to be dangerous.

When you are striving for something, the action is out on a limb.  The danger is that you are doing something new and you're initially uncomfortable going further and further out on that limb.  Just like with anything you've ever learned, balancing on the limb, the growth of the limb, and your knowledge grows.  Not overnight, not in a week, but in time.  You can feed the tree that holds your limb by learning more about what you are doing right (and wrong) and become so accustomed to living on the limb (where the most sunshine is), that the thought of returning to the trunk and climbing back to earth is evening more frightening than being precariously balanced with the wind blowing.
