Step One: You Have One
For some, this seems to be the most difficult step. Maybe you're not an artist/musician/writer so you think you don't have a muse. Wrong. Everyone does. Just because yours is different than the media portrayal of the Muse, doesn't mean that she* doesn't exist. What media portrayal currently describes your struggles and your life right now? What, none? Exactly.
My mom's muse couldn't be arsed with airy-fairy art junk. She's got snarled balls of yarn being delicately barfed up onto her desk by management, full of knots and tangles and a lack of fucks to give about current tax codes. It's up to my mom (and her muse) to wrangle that hot mess into order. My mom's muse answers to the name Mrs. Peel and dreams in numbers.
