The prison is in your head, you can be way more than you currently are if you convince yourself of it. Your self-projection will drive you forward more than your habits as it gives you the will to continue during hard times. The goal is not to appear a certain way around others or in front of a mirror but to connect with your ideal true self. Over time and continuous actions, you will become your myth and realize everything is possible. Greeks had Odysseus, Romans had Hercules, Celtics had Arthur, you have you.
