The unexamined life may not be worth living, but the over examined life isn’t worth living either. 
Isn’t it interesting how two people can look at the same experience and see it completely differently? How is it that 2 prisoners of war with similar experiences can come out of the ordeal and one has PTSD while the other emerges strong and resilient?
I think some people let past experiences spill into their everyday life, while others compartmentalize their past into tiny little boxes. Some people tie their identity to things that make them feel like they are not in control, that things happen to them, that they must continue to endure what has already happened. The past is as in front of them as it is behind them.
Other people see past events in a metaphorical rear view window… there when you are looking at it, but the memories in the reflection seem distant. And the mirror is somewhere in your peripheral vision when you aren’t looking, and easy to forget to pay attention to, unless there is a reason to look back.
A loss of someone you love can haunt you, or it can provoke feelings of love and fond memories. A loss of limb can leave one person devastated with respect to what they can no longer do, and another person is left thankful for what they still can do. Both of these are painful things to endure. But the frame around the experiences can be very different. Two people and one experience. One frames the experiences into tiny little boxes, the other lets the past experience spill into new experiences.
Do we get to decide? Or are we wired a certain way? Maybe a bit of both.
Does our upbringing influence our ability to cope? Certainly! Trauma transcends generations, and growing up in a psychologically unhealthy environment will impact one’s ability to cope. Tiny boxes aren’t built in stressful environments, and it’s hard to ignore the rear view mirror when you are constantly reminded that objects there are much closer than they appear.
But there is always an opportunity to wrap things up in tiny little boxes… still there, still available, just not spilled out into the present when the memories don’t enrich the current moment. Because when we spend too much time looking in the rear view mirror, it’s hard to see the road ahead.
