Will-power is essentially an Interplay between multiple models. If you view days as test-runs for programs you have optionally installed in your system, the energetic focalizers are creating energetic "gravity-tag games" out of synergystic signal processing. Let's say you have a process already needing to be in motion and then you attach a carrier wave on top of that...it could be considered a supplemental annex which creates an alternative nexus point for another energy loop or process table.

Anyway, move marginally beyond the words I'm using and imagine it more as an attractor where you go down a river on a riverboat and while casting nets also change your duck call to another one which still attracs ducks but also happens to attract alligators. Taking advantage of overlapping scenarios to create a change in what the existing momentum is applied to is the real trick of conscious agents.
