There's no reason to defend anger or make excuses for it. Don't claim it's useful or unavoidable. Every vice has its defenders — that doesn't make anger acceptable. The problems we face can be fixed. We were born with a natural lean toward good, and nature will help us if we try to improve ourselves. The path to virtue isn't steep and rocky like some people think. You can reach it on level ground. I'm not telling you fairy tales here. The road to happiness is easy. Just start walking it with good fortune and the gods' help. What you're doing now — staying angry — is much harder work.
There is no reason why we should seek to defend such a passion as this or excuse its excesses by declaring it to be either useful or unavoidable. What vice, indeed, is without its defenders? yet this is no reason why you should declare anger to be ineradicable. The evils from which we suffer are curable, and since we were born with a natural bias towards good, nature herself will help us if we try to amend our lives. Nor is the path to virtue steep and rough, as some think it to be: it may be reached on level ground. This is no untrue tale which I come to tell you: the road to happiness is easy; do you only enter upon it with good luck and the good help of the gods themselves. It is much harder to do what you are doing.
