Assurance

Before changing, a person will want assurance that it is in his or her interest to do so.  The interest of the therapist or that of the broader society is not an issue.  It must suit the individual's very unique requirements and may need even to be at odds with the ordinary judgment of people.  The change is the issue, not the specific motivation for it.  Of course, there never can be sufficient assurance and the jump is always into uncertainty.
