The best way to escape from the past is not to avoid or forget it, but to accept and forgive it.
One of the foremost approaches to learning in life is to make new decisions based off of previous experiences. It starts when we are young, many of us may have tried to draw near or even touch a hot stove not knowing that we would get burned, and then from that experience learn to stay away from touching hot burning stoves with no protection. This is an example of how we use our past mistakes to determine what decisions to make in our future. It is imperative that we draw from our experiences so that we won't get burned again.
