It is hard to find justification but when we look closely enough we realize that it is our own karma that we are reaping. Our pain holds key clues to our purpose for living. What is your pain and how can you transform it is the question you must ask yourself. We each have our own stuff. My stuff may come in a different form than someone elses but in essence the experience is the same.
Fear never changes anything.
Action changes things. Change of perception changes things. Doing something changes things. Whatever your vision is take steps toward that end. However, if what you are aiming for does not include other people then I would say you are aiming for the wrong thing.
