Think of your Soul Body as your inner self and your very best friend. It's also your intuitive, creative, happy, infinite and compassionate self. So if your soul body is not in balance, you'll feel it right away. As a creative person, you'll feel out of sorts, at a loss for what to do, you might lack inspiration or ideas or feel blocked. Creatives must keep connected to the first body because it is the source of the Creative Flow. If you are creatively blocked, the soul body will get you hooked up!
"Creativity is the journey of the self reconnecting with the soul's vibration" - William Blake
