After watching a documentary about the Actors Studio, you know, the Stanislavsky method

What if we already lived what we had to live? What if the best moment of our lives, its meaning, has already happened? What if it happened three years ago, and you know that was it, and you knew even better afterwards, and now you can only lie to yourself in order to enjoy? There's no enjoyment when you know that. There can't be. It's gone, what is to come is just the remainings. Nothing else will matter as much as it mattered back then. Now, just the remainings... figure out how to avoid too much suffering till the end comes.
