Boundaries are created from our fears and serve as a way to shield us from potential harm. They are a form of protection that we establish in response to our anxieties and uncertainties. These limits can influence how we interact with others and how we perceive the world around us.
However, the author expresses a desire to move beyond these protective barriers, seeking instead a sense of freedom. In her view, true liberation involves breaking down these fear-based boundaries to experience the full scope of life's possibilities and the natural world, as inspired by America's national parks.
