Everyone is shaped by life experiences. We usually think about how this makes us different, rather than how we would be if we lived another's life. We have to consider their entire life story, not just their present condition: much more than just "walking in their shoes."

The universe is governed by probability. Most consequences of our choices are not extremely good or bad, so we tend not to think of them as consequences. we only interrogate our choices when they lead to an unusual result. We try to find explanations when luck/chance might do.
