I take the main motivation equation to be illustrative only. You may assign units like utilons/time or whatever but I think that human motivation is highly nonlinear with logistic satiation effects and multiple effects at differnent time scales.
Just have a look at the graphs in Human Motivation:
In that case, the equation is misleading and really shouldn’t be used at all. This seems to be a common issue with self-help books and the like: sprinkling in equations for “mathiness points”, without actually thinking about things like what the units would be, or whether it actually matches up as a model. The “Happiness Equation” is another example.
