The fundamental law of power is that it is situational, multifaceted, dynamic, and perishable.
Power is Situational
Power is without a doubt situational, a person who is very politically powerful, but having no wilderness knowledge or skills, find themselves alone in the middle will have less ability to save themselves, than an experienced woodsman.
Power is Multifaceted
Power has many attributes (social influence, mental reference, innate ability, and situation), which aggregate to provide the total of your power at in given time and in any given situation
Power is Dynamic
As a person’s situation changes, their ability to influence the situation can be increased, decreased, and/or lost. Also, facets of power are not static but are morphed by change.
Power is Perishable
A person can, through inaction, lose the ability to influence a situation forever.
