There are also already some fields that touch on this, such as the recent Creativity & Artistic Expression.
This field isn’t ‘wiring’, but directly addresses your thoughts regarding the resolve and energy to do the work, ‘sparking’ inspiration and even the ability to convey your thoughts and concepts through the work.
Besides this, there are an assortment of other Creativity fields such as The Well of Creativity and the OG Induce Creativity field that specifically mentions it improves your long term creative potentials. You could try Archangel Gabriel or other Intercession fields too for that ‘abstract thinking’ or ‘beyond yourself’ perspective.
There are undoubtedly many mechanisms for inducing a ‘state’ of ‘creativity’ and while ‘brain wiring’ them could certainly be one of them, perhaps it isn’t the right brush to paint with on this subject.
Not without more definition, in any case!
