La vérité, Boris Cyrulnik [The truth To find happiness, you have to risk misfortune. If you want to be happy, we must not seek to flee misfortune at all costs. We should rather investigate how - and thanks to that - we can overcome it.
Never regret having known a person in life. The good ones give you happiness, bad ones give you experience and the most wicked give you a lesson. In any case, you win something and you can never be a loser.
