I think creativity, to some extent, is to create order out of chaos. But too much chaos can be frustrating. At least, that goes for me, and especially when I´m stressed out.
But during those times, I need to create even more.
And so, I found out a way to create in chaos, by blocking out some of it. I turn off the roof light and work in a spotlight. When I can´t see the surroundings so well, I can manage to ignore it.
Maybe it works for you to?
