Aye, creative block is one big struggle for writers and artists alike. Creative block is not solved by plain sitting around and staring at one’s medium all day. It requires doing something different — something that is a new experience and understanding for artists.
Over time, artists have used muses for creating new products. Some try to learn something new and some try not to compare their work against others they regard as superior to theirs. Remember, in art, there is nothing superior — and new experiences and an understanding of the world is all that matters.
