My motto

"Der Weg ist das Ziel" (The journey is the goal) Chinese saying, unknown origin

"No shred of evidence exists in favor of the argument that life is serious, though it is often hard and even terrible. And saying that, I am prompted to add what follows out of it: that since everything ends badly for us, in the inescapable tragedy of death, it seems obvious that the first rule of life is to have a good time." --Brendan Gill
