Honestly looking back at choices made isn't a good thing most of the time, knowing hindsight will always be 20/20. Thinking back to that time and remembering, what other choices were there to pick from. 9 times out 10 it was the best choice out the choices at that time. Judging the choices made, isn't really fair not being the same person now. In part because of each choice made over the years, it's not like anyone can go back in time to fix or right any wrong. Seeing it as a regret the choice is, wasting time rethinking history like it's could changed or learn from it and move on forward.
Every choice made is a path not taken the choices made helped us become who we are. Where we go from here, is guided by the choices we make from this point on. Our history is the sign post showing us how far we have come, and how far we have to go. It's a journey that we have a life time to complete, a work in process continued by each choice made. I for one am enjoying the ride
