Feelings are sacred. They are your barometer for what's really important. Keep a journal. Make friends with your feelings. Pay attention when you're enthusiastic.
Studies show that people with enthusiasm have stronger immune systems because they're high on life.
When you feel this way, your soul is speaking, you feel endless energy, exhilaration. To find your passion, tune into your enthusiasm. Pay attention to synchronicities. The German poet Goethe said that once you commit yourself to something, then providence moves too. All sorts of things occur to help you that otherwise would never have occurred.
