As a Catholic, I never really believed in karma nor did I relish the idea of seeking revenge. Jesus turned the other cheek, and so should we. Maybe the person who wronged you will eventually regret it, or maybe their life will turn out fabulous. Maybe a little bit of both or none of the above. But it shouldn’t be your concern. The best thing to do is forgive them, let it go, and focus on your own life. Success is the best revenge.
