Here is a lighthearted, and very brief, look at basic psychological needs and the approach/avoid mechanisms of enhancing or protecting those needs. The model I use is loosely based on the consistency theory of Klaus Grawe with some additions (like overlapping needs) that Dr. Pieter Rossouw and myself have talked about and which Pieter has explained in more depth in his latest book, the details of which you can find here.

You can find out more about the consistency theory here

And in case you were thinking it - yes, I look very tired on this video! Maybe I need to yield to the physical need for sleep and override the psychological need to enhance the pleasure of sharing this information with you lol.
