I don't really know how intrinsic motivation could be controlled in the same fashion. A motivated and euphoric teacher maybe can achieve the same in the other direction, but I guess there will always be a certain kind of predisposition and "talent" to be motivated for a specific field.
Would love to know how I can design those predispositions to change my own behavior. I guess behavioral therapy could work, but that's hellofa lot effort to learn some math.
