Life is filled with unanswered questions, but it is the courage to seek those answers that continues to give meaning to life. You can spend your life wallowing in despair, wondering why you were the one who was led towards the road strewn with pain, or you can be grateful that you are strong enough to survive it.
Make it a rule of life never to regret and never to look back. Regret is an appalling waste of energy; you can't build on it; it's only for wallowing in.
"Every man has his price." This is not true. But for every man there exists a bait which he cannot resist swallowing. To win over certain people to something, it is only necessary to give it a gloss of love of humanity, nobility, gentleness, self-sacrifice - and there is nothing you cannot get them to swallow. To their souls, these are the icing, the tidbit; other kinds of souls have others.
