5 - Give it a break: That's right, a good way to get artistically inspired is to stop trying to get artistically inspired. Go read a book or do some yoga or organize your studio or learn to juggle. Maybe even for a few days. Sometimes forcing the next 'great idea' will actually do the opposite since our brains can freeze under too much pressure.
That being said, any professional artist will tell you at some point you must 'paint through the pain' and keep working in order to maintain all the hard work flow that goes into being a successful artist, but little breaks are ok. Hopefully you'll have some emails to send, blogs to write, or art supplies to shop for that will make your time away from the studio productive still. (I'm an avid hula hooper in my free time; it's a wonderfully meditative yet energetic way to free my dancing spirit!)
6 - Check up on your favorite artists: Assuming you have favorite living artists still producing work, go pop in on their websites and blogs. See what they're doing these days as far as subject matter, themed group shows, workshops, or possibly even changing up and evolving their styles a bit. If you don't have favorite living artists, go find some!! There are sooooo many incredible people creating so many great works in this day and age.
Some good ways to find new artists are by following up on any works that stood out from shows you've seen in person, by following and subscribing to contemporary art mags (like Juxtapoz, Art Collector Magazine, Aesthetica, or ARTnews), and by surfing social media like Instagram to see what your like-minded friend folks are liking (find me on there too! @caleighbirdart).
