You can tell a lot about a person by what gets him mad.

I tend to get mad about inconvenience and incompetence. Manila traffic, baristas who mess up my latte, and loooong security lines at the airport—especially when I get behind the infrequent flyer who slowly pulls yet another forbidden metal object from his bottomless pocket.

In the grand scheme of things, too much foam in my latte and a missed flight don’t really matter. What I should get angry about is INJUSTICE. But too often I’ve used up all my anger on the trivial and temporal.

Lesson from Saul: he knew when to get angry. (See 1 Samuel 11 where Saul “BURNED WITH ANGER” over injustice.)

What gets you mad—inconvenience, incompetence, or injustice?
