This step does state this.  The Big Book tells us that this Step “separates the men from the boys”.  It recognises the high level  requirement  from a spiritual and emotional place.  The importance to be willing to behave differently from the ways of the past.  Is one willing to change in order to be changed?  The development of more and more willingness to have defects removed is a lifelong process.  It is cyclical in terms of “my Will” “Thy Will”.  The changing of script is similar in that it requires the same emotional demands and faith in the process.  Often peoples work on life script changes hold many situations that can not be explained in a rational way but hold a spiritual connection.  For example working on death anxiety and a friend gets cancer or having existential angst and then checking your birth certificate to see that sister was mother.  As we awake spiritually we seem to parallel a process by waking up to our scripts and the real fabric of there construction.  To be real and embrace this change to reach full potential its often not for the faint hearted.  I see in my work really tough candidates that want to change script “if they really want to they will”.  Just like addicts that really want recovery.  They also have tough trauma and pain from their experiences that have led them to wanting the changes.  Again “if they really want recovery” then they will succeed.  Even if one goes of track its not a failure depending on what is done with the learning.  To be willing to see the habitual interpretations we apply to situations in our script.  This is similar to looking at the habitual defects of character that relate to relapse. ITS TOUGH BUT ALL WORTH IT.
