A penniless man who has no ties to bind him is master of himself at any rate, but a luckless wretch who is in love no longer belongs to himself, and may not take his own life. Love makes us almost sacred in our own eyes; it is the life of another that we revere within us; then and so begins for us the cruelest trouble of all.
Consider that nothing in human life is stable; for then you will not exult overmuch in prosperity, nor grieve overmuch in adversity. Rejoice over the good things which come to you, but grieve in moderation over the evils which befall you.
