I'd say it's rather difficult to ''look'' for a muse. It's something that just happens. You see someone/something and you feel a click within you - that's when the magic begins. Although I'd suggest going to places that are connected with your preferred artform, as in music halls if you're a musician, galleries if you're an artist and so forth. You're bound to find at least a bit of inspiration, or if you're lucky, a muse of your own in such places. Best of luck to you!
