A constructive or destructive new life?

I was Studying for Algorithms and Data Structures trying to learn the concept of constructive and destrucitve ADT's When I thought that we could relate in the same way to our lives.

Constructive ADT in Computer science refers to A new object (method) being created to store the changes of the original method called upon, leaving the original method unchanged.

Destructive ADT is when the original method called is changed (Hence its original order destructed).

I was thinking about positive changes in ones life, if one was to go about them.. would he construct a new method, or way of life to improve on what he was lacking, or to implement the change, or would he completely destroy his original way of life, yet continue living in the same way? If the change was constructive then would some aspects of the old life be unchanged? If they are unchanged and become a memory of the past, will they still have any affect on the persons new life?

What method of change would you have? Constructive or destructive?
