The photo is about your ideas (Sounds a little bit weird?). When you don’t think or you don’t want to think those small people takes your ideas out of your brain but when you are thinking, those small people in your mind can’t get those ideas.On the photo those balls are your ideas, if you not thinking they are going out of your brain.Easy, less you thinking less you got ideas.The light bulb, like in movies when someone got idea or trying to think you will find it and when they don’t think you will not see it.
