As people, we are always changing and making an effort to survive. Avoiding death is part of life as we slowly move towards.
Yet there is a term of being dead inside. A state of emotion that is stagnant and is very much dead. Yet with persistence, we have continued to move forward and this is part of our own nature.
Moving with our legs. If no legs are given to us we make do with any other means. Persistence is the core of not fading away and any effort to move to another day is upheld by this.
