The most common mistake made by these modern advisors is the tendency to turn a habit recognized as healthy into a universal recommendation. From psychology to medicine, the excellent professional is the one who can best adapt to the individual circumstances he encounters.

In other words, it is a task that almost always involves more understanding of a unique and new situation than applying a standard protocol.
