Anger

What is more unworthy of the wise man than that his emotions should depend on the wickedness of others? Shall great Socrates lose the power to carry back home the same look he had when he left? If the wise man is to be angered by low deeds, if he is to upset and unsettled by crimes, surely nothing is more woeful than the wise man’s lot; his whole life will be passed in anger and in grief. For what moment will there be when he will not see something to disaaprove of?

— Seneca, On Anger 2.7.1

As I have noted, I have been focused on the gravity of forgiveness and grace. Grace is a choice. You do choose to love others and to ignore or accept the small stuff and to love and work on the bigger challenges. It is a mindset. 

The opposite of grace is also a mindset. Once you choose to be angry there is always something to be angry about. The anger will never end. As my friend noted, ignore the little things and work on the bigger things. Do not start down the road of anger.
