Have you ever had a light bulb moment when something suddenly became apparent, the fog lifted, and you were able to see it more clearly?
At times I have no ideas for new art pieces. But at some point later those ideas arrive and I can create something again. I was in a similar situation with solving puzzles. At times pieces just doesn't seem to fit with one another. Other times for a while every puzzle piece I pick fits perfectly.
When the light bulbs goes on, figuratively, it's really cool as one can push on with things and that's when we make great achievements.
