Prometheus 6

I feel the appeal of this model

On the other hand

The purpose of this diagram is not to be mean, not to be a bringdown. We're not trying to make sensitive little girls depressed. The purpose of this diagram is to convince you earnestly and in all sincerity that there is NO HOPE so that you will be transformed by the cold hard truth. Once you accept the reality of NO HOPE you can begin to approach your life in a new way. Now you can take your head out of the clouds, quit looking to some illusion of a perfect future [P6: or past], and start living in the present [P6: keeping in mind the edges of now are contextual, and a little blurry at best]. Knowing that there is, in fact, NO HOPE, and feeling this great realization wioth your whole being will slam you back to the real world like you've never been before. Come on! You can handle it!
