The classic work of Jewish Ethics, "Path of the Just," says: "Every aspect of our lives is a challenge and test."
With this perspective, life will never be boring or mundane. Every single situation and occurrence is different from every other - and each is an opportunity for elevation and growth.
When you are aware that a situation is a test, you will find it much easier to deal with. To illustrate this concept, imagine that you went for a job interview and the potential employer shouted an insult at you. You would most probably feel either upset or angry. But if someone told you in advance that this employer shouts at job candidates to test their reaction to stress, you would find it easy to remain calm. You realize it is just a test and it is in your best interests to pass it.
That is how we can view each event and situation. It is a test of our spiritual strength and courage, and we can look forward to passing it.
