if someone tells you do not think of a white elephant, what are you going to think about ?
a white elephant of course.

I do believe this is a key to understanding the cerebellum, the part of the brain in charge of actual actions
this part can use -+ motivations to decide on engaging thoughts and optimizing the execution.

much like the lego ev3 and lego 51515 programing language in which
you have 3 parts :
a track summoner, which also decides if to execute an action
code block parts
and an index to point along said tracks.
