I can not imagine choosing to make yourself angry. I can't imagine abusing myself that way. Value yourself and your practices and instead of pacing at cage bars and snarling, support and rally behind what you believe in. Give your attention and love to the causes and cures that make this world better. Be a force for positivity and you will be amazed at the life that surrounds you because of that choice. Do not waste a minute on the things that bring you down or offend you. You're wasting everyone's precious time. Most of all, your own.
We are defined by the decisions we make.
