I think it is important to stress as an addendum to The Lizard's point that you must search for meaning and adventure in everything you do, with the job itself simply being a vehicle for the partial attainment of this. I'm reminded of the lines at the start of 'The Death of Ilya Ilych', where Tolstoy writes that Ilya Ilych's life had been 'most simple and most ordinary and therefore most terrible'. Real significance and the ability to manifest it is already within you. Your job is simply one scratching post for you to sharpen your metaphysical claws upon.
