I think the majority of people would agree that it's unhealthy to live in the past. After all, we're all familiar with the new age philosophy, “Yesterday is history, tomorrow is a mystery, but today is a gift____Living in the past holds us back from being able to enjoy the present moment. But are there any benefits of revisiting a previous time? Actually, yes. The past has several advantages:

     Learning from our mistakes: We all know that poor choices can be some of life's greatest teachers____

    ____By revisiting an unfavorable event from our past, we can often view it from a different perspective as time has passed. Being older and wiser, we are now able to reevaluate the experience and gain deeper insights and understandings of what happened and why, and how it has impacted us since. What once scarred us can now be healed through a newly-found awareness and no longer be a negative force in our lives.

    Motivated by earlier successes____Other times life has been difficult. Remembering the past when we were at our best can help motivate us out of our current slump(低谷) and put us back on track for success. Use your past successes to propel(推动) you on to newer and greater things.

    While it's evident that revisiting the past has several advantages, there is a warning. Just like an amusement park, it's fine to visit but you cannot stay there forever. At some point, the park closes and all visitors are asked to leave. Enjoy the past when necessary but don't always stay there. Use it for living in the present and planning for the future____

A. Moving beyond

B. That's why it's called the present

C. In that way, it will serve you well

D. See the mistakes as a step on the road to a solution

E. There are times when we have all enjoyed success on a variety of levels

F. Recalling times when we made mistakes can help us make better future decisions

G. So, failure is the mother of success
