It isn't necessarily a good thing if your job is a breeze. If you have mastered your job to the point that you can do it in your sleep, then it might be time to wake yourself up. Developing yourself requires new challenges, and if work isn't providing you with new mountains to climb and hurdles to jump, it might be time to seek new opportunities. Comfort is extremely appealing and there are few things in life that feel better than being valued in the workplace, but, if the work is too easy, you probably aren't getting better. Seeking out new challenges can be incredibly intimidating, because you are choosing to leave something you know well for the great unknown. The odds are that you'll be happier once you strike out on new adventures because life is incredibly dull if you're not pushing yourself.
