If you’re not feeling creative try not to stress about it. I waste half a day looking for excuses as to why I’m feeling this way instead of just sitting down and doing. Once you sit down and pick up a pencil just start drawing lines, think playful, think goofing off or doodling. At least you’re doing something and usually when I do this, something usually starts flowing and I’m creating again. You just have to stop over-thinking and just start.
