Never to doubt about your possibilities, never be broken down by the temporary reality that it is not all about world. You still have many possibilities to be anyone, to go many places and see many sights you could not imagine, life is not just what looking out of your house window.
I have recently begun to think that each human being is not single, all human beings together are one life. We are like cells in a giant that is constantly moving forward, where a single life falls and another life rises. Human beings are immortal, and what happens to them uniquely is repeated in the lives of others, his character, his preferences, him and everything about him, it just like he fades away, but he becomes countless molecules, and all the episodes and pursuits and details about him are scattered over and over again in the human beings of the past or of the future. Thinking in this way, we do not have to feel irreparably saddened by the death of a single life.
From a micro perspective, we are just cells of a giant, on the condition that we do not harm others, that nothing can bind us and any place can be home, no one is really asking us to see only this one window view for the rest of our lives; from a macro perspective, we are a giant, we are everyone, we are all, we are both the cells and the universe. We are the home inside the windows.
