Systems Language - causal connection

Technical note only...for equilibrium I think you need sources of time as well as uses (i.e., activity) of time.
Model note...where does sleep factor in? Both study time and sports time could expand as sleep contracts. Sets up a realistic feedback loop, likely time delayed. So far (as I read it) the model is just adjusting pieces of a constant size pie. Sleep might grow or shrink the pie.
I suspect, but do not know for sure, that Grades and Basketball skill will both follow an S-shaped curve in response to time. Table function?
Also, there is metabolic energy (nutrients, rest, general wellness, etc.) and psychic energy (energized by accomplishment, etc.). Ought not that be a feedback loop factor also?
Depending on Mum's bent of mind, could not her approval be opposite of what you depict?
Finally, I like the self approval flow, very self-actualized if I may say so . At that age, would not an external locus of control come into play?
Regards,
Bill
