This is, in simplified form, the Problem-Solving Model!
The large circle ("You") includes Need (and could include Personal Block).
The arrow labeled "Activity" is pretty obvious.
The block is a Block in the World.
"Goal" is Goal State.
The small circle with arrow is Help, of course, assisting activity to circumvent the block.
The dotted line above refers to the Anticipation subcats.
For those who had a hard time following my verbal version, use the model visually. If you take out Activity, what you have is You, Anticipation, a Goal, yes, but a lot of Blocks. This is helplessness! I can see what to do, but can't do it, not only because I anticipate failure and can see every reason why, but also because I lack action that could carry me through regardless.
If, on the other hand, a story lacks all the Anticipation and Block imagery, what you may have is someone who drives to the goal, but collides with unanticipated obstacles!
And so forth...
