If you could return to the past to relive a part of your life, either to experience the wonderful bits again or to do something over, which part of your life would you return to and why?
Regrets?
Personally, I Have no desire to travel into my past glimpsing of times good or bad.
Joyful times, tragedies and regrets, developed wisdom, shaping who, I am.
Forgoing incredible temptations, affecting the present filled with family and friends.
Using wisdom and memory, along with video and audio capturing my past to be preserved without regrets.
