If we apply the concept itself of negentropy itself as an idea, and apply it to the answer of the question. What would be the best way, to create a situation where the outcome is gonna be in your favor. Yet, without influencing the people around you directly.
As, that is never really a good idea.
But how about creating a positive environment that invites abundance and positive outcomes, all wrapped in a bundle of feeling welcomed, personally invited and in rapport with those around you.
Uses I imagine can range from, before meeting preparations, store ambience, meeting somebody new, etc etc.
This affects the environment and the people in the environment.
Loop as needed.
