we use to deal with these 2 different kinds of projects: Chronic and Acute.
A chronic project is present in a person's life for a long time and invites us to find the hidden cause that produces specific effects.
An acute project, on the other hand, represents something new in a person's life. It is much easier to help, and the cause is not hidden as deep as the Chronic one.
That is the reason is important for the student/practitioner be prepared to face the challenges each one proposed.
