The Gurus will tell you that you should work on being fully aligned - heart, head, spirit, and that you should seek inner peace. That's nice. I mean, really.
But you know, it turns out that frustration, fear, pain, worry, doubt, guilt - yes, all of these are useful things. Some of our best creative work comes from conflict, comes from the darker side of the feeling spectrum.
What's great about the creative life, is that everything can be used, everything can be channeled, all life is just so mulch for our creative projects. Creativity is all-inclusive, all-consuming, everything counts.
