Only people who are not happy with themselves are mean to others. Remember that.
“What you must understand about me is that I’m a deeply unhappy person.”― John Green
“No one should ever ask themselves that: why am I unhappy? The question carries within it the virus that will destroy everything. If we ask that question, it means we want to find out what makes us happy. If what makes us happy is different from what we have now, then we must either change once and for all or stay as we are, feeling even more unhappy.”― Paulo Coelho
“Happiness is a garden walled with glass: there's no way in or out. In Paradise there are no stories, because there are no journeys. It's loss and regret and misery and yearning that drive the story forward, along its twisted road.” ― Margaret Atwood
