Good ideas don’t come out consecutively.
They come out buried in a stream of other absolutely terrible ideas.
So if you stop creating because the last idea was shit, you’ve stopped at exactly the wrong moment.
Writer’s block is expecting every single idea you produce to be good.
The solution is to keep the creative pipe flowing and allowing yourself to get the sludge out so the great ideas can flow from behind.
You don’t have to show everything you make.
