Although it is very hard to control our moods, we can gradually overcome them by living a well-disciplined spiritual life. This can prevent us from acting out of our moods. We might not "feel" like getting up in the morning because we "feel" that life is not worth living, that nobody loves us, and that our work is boring. But if we get up anyhow, to spend some time reading the Gospels, praying the Psalms, and thanking God for a new day, our moods may lose their power over us.
For further reflection...
