A concept from Mastery. Primal Inclinations refer to those activities or subjects that deeply interest us, and especially interested us as we were kids. These activities or subjects could be things like writing, playing with certain toys, reading about certain scientific fields, building things.
Albert Einstein, for example, was fascinated as an early child with a compass that his father had given him, and it was from that fascination that he developed a deep interest in physics. For Greene, one of the main ways to find your life’s task – your calling in life – is to look at your primal inclinations – those subjects or activities that really fascinate you or drew your attention as a child.
