The current emphasis on quick fix solutions, be that for counselling and psychotherapy, for diets or for exercise programmes is understandable but misleading. It is part of a cultural movement like Instagram and Twitter.
Whereas one can be bullish about setting targets that appeal to our egos and our vanity, what we are trying to work with, when we look for longer and more sustained change are deeper layers of ourselves, the dimension of psyche.
The pace and length of psychotherapy or counselling treatment is likely to be linked to the problem being faced. Some problems are more obvious than others. So a traumatic event, a sudden change, may soften and become easier to absorb once it has been come to terms with, but coming to terms with it may take time.
