Hurt people hurt people. That’s a cycle we historically keep feeding and perpetuating. If we are truly evolving, and becoming better as a species, then we, as individuals, must learn to break that cycle.
It takes true strength to be kind. And courage. If you don’t believe me, try to be kind when someone lashes out to you, and see how long you last before you’re compelled to retaliate. It’s easier to give in than to hold out. Nothing in life worth having is easy.
