“I would say, that I am applying the ‘butterfly wing’ theory to my everyday life.  It’s a kind of moral dictum, moral responsibility to keep in mind that whatever I do this second affects what the next second will be.  So I try not to do anything negative, which is my best insurance that the world will be better next second, or at least not worse.  But of course, my positive action may be undermined by 100 negative actions of others and so it may mean nothing.  But I still have to follow that dictum.  You can call it optimism.” ~ Jonas Mekas, via Happiness is a Choice You Make (Page 212)
