" Happy is not the right word. This world is not a place where we can be happy. It wasn’t created for man’s happiness, though many believe this is the reason of our existence. I think we are here to fight, so that good and evil can clash within us, and good may prevail, thus enriching us spiritually. It’s difficult to say whether we are happy or not: it doesn’t depend on us… There are times when one regrets being born, but life also gives us surprising things that, alone, are worth living. The issue of happiness doesn’t exist for me: happiness as such doesn’t exist. "

― Andrei Tarkovsky
