Other artists and creative people inspire me to write. A photo, a painting or a poem will often open windows in my mind. Feedback from other people is also not only encouraging but inspiring too.
Over the past couple of years I've subscribed to a free 'zine that features creative people - photographers, poets, novelists and painters. It's called Ends of the Earth and is available by email subscription at email@example.com if you're interested. It's sole purpose is promote high quality creative work.
There are 3 issues each year in April, August and December. This year I have had 2 poems featured in the April and August editions. In the December issue I have a poem and a short story about Dracomagan.
Feedback from other artists as well as non-artists is very important to me. It shows me where I should be going next and reaffirms when I've created something that has a wide audience appeal.
Even if the feedback is short and sweet, such as I liked that, it means a lot.
