Te ne metto un paio (in inglese ma al bisogno te le traduco, eh...)
"Happiness is the consequence of personal effort. You fight for it, strive for it, insist upon it, and sometimes even travel around the world looking for it. You have to participate relentlessly in the manifestations of your own blessings. And once you have achieved a state of happiness, you must never become lax about maintaining it. You must make a mighty effort to keep swimming upward into that happiness forever, to stay afloat on top of it."
— Elizabeth Gilbert (Eat, Pray, Love)
"We search for happiness everywhere, but we are like Tolstoy's fabled beggar who spent his life sitting on a pot of gold, under him the whole time. Your treasure--your perfection--is within you already. But to claim it, you must leave the buy commotion of the mind and abandon the desires of the ego and enter into the silence of the heart."
— Elizabeth Gilbert (Eat, Pray, Love: One Woman's Search for Everything Across Italy, India and Indonesia)
"You were given life; it is your duty (and also your entitlement as a human being) to find something beautiful within life, no matter how slight."
— Elizabeth Gilbert
