Life has no meaning unless we give it meaning.
Systems have sub-systems and sub-systems have sub- systems and so on ad infinitum - which is why we're always starting over.
释义:开始时做得好的人确实很多,但能够坚持到底的人却很少。这句话揭示了人们在做事过程中往往容易虎头蛇尾,难以善始善终。 
It's all about trying to make something that's as complex and as true to life as possible.
