What do you do?
This has happened to me before. When it did, I took a step back from my own work and became inspired by the work of other creative people; in person, in print, and online. After a while of doing this in a purposeful way, ideas began to percolate, I began sketching, and new directions emerged.
So, do that again, you say. And, you're right. I have been, but it hasn't worked so far.
What's the larger issue, you ask. Ah, good question.
So, that's my dilemma. Any ideas? Suggestions? Words of wisdom?
