Walls are a visual representation of the guards that we're putting up. You can look at it like a layer of protection that we built around an excuse, a reason why we're not where we want to be or why something is unattainable for us. What are your walls representing, why did you build them and what are they really protecting? In order for us to change a habit or learn a new behavior, we need to gain a deeper understanding of what the layers around the goal are and why we haven't been able to break through the walls of our old conditioning and beliefs.
