Lately, I've been trying to train myself to react to any trial by asking a simple question, "Which is more important to me, Olam Hazeh or Olam Haba?” The answer, obviously, is the latter. This goes back to a Moshol I saw many years ago in the Chovos HaLevavos, comparing the relationship between Olam Hazeh and Olam Haba to a man with two wives: The more he makes one of them happy, the more he upsets the other one.
That's just the way it is.
