What we often, depends on are what we have been. Current decisions are built on past experiences. We are all victims of our experiences.
“Victims” because good (or bad) experiences in the past make us extrapolate that to the future. Victims because this can lead us to make bad choices/decisions. Our optimism or pessimism depends on our past.
“We are products of our past, but we don’t have to be prisoners of it.” ― Rick Warren, The Purpose Driven Life: What on Earth Am I Here for?
