@Amaral I think you're referring to the concept of Flow.
(from Wiki)
http://en.wikipedia.org/wiki/Flow_%28psychology%29
Flow is the mental state of operation in which a person in an activity is fully immersed in a
feeling of energized focus, full involvement, and success in the process
of the activity. Proposed by Csíkszentmihályi the positive psychology concept has been widely referenced across a variety of fields.
According to Csíkszentmihályi, flow is completely focused motivation. It is a single-minded immersion and represents perhaps the ultimate in harnessing the emotions in the service of performing and learning.
In flow, the emotions are not just contained and channeled, but
positive, energized, and aligned with the task at hand. To be caught in
the ennui of depression or the agitation of anxiety is to be barred from flow. The hallmark of flow is a feeling of spontaneous joy, even rapture, while performing a task although flow is also described (below) as a deep focus on nothing but the activity - not even oneself or one's emotions.
He has written an entire book about Flow and creativity actually 😃 (Csíkszentmihályi, Mihály (1996), Creativity: Flow and the Psychology of Discovery and Invention) I read it, but if you're interested I'd personally recommend his first, more general book (Csíkszentmihályi, Mihály (1990), Flow: The Psychology of Optimal Experience)
So an an artist you have no problems with motivation then? We should talk 😃
