The tipoff for me is somatic. Whenever a project comes to me, one that is right, that is genuine, I feel a kind of “shiver” in my body, and that tells me that it corresponds to something very deep in me, and that I need to pursue it. That has been my guide with literally every book I wrote. Trusting this kind of visceral reaction means that you are willing to let life “come and get you.” It means who you are is defined from the inside, not the outside. In terms of what’s really important, we don’t have much choice, and that’s as it should be. The decision is made by a larger energy or unconscious process, and when it’s right, you know it… Goethe wrote: “Man errs as long as he strives.” Sit still, meditate, just let the answer arise from the body. (It may take a while.)
