Work - to live

We all work. .either for someone or for our self. .the question is "Do we live to work OR Work to live?". I know and have seen folks working late nights to ensure that they get a great performance review. Hope is that when they get a good review, a salary hike wil follow and can take their families out on a vacation. .BUT. .since he got a good review, he is expected to work more and more. .We normally would think and plan and plan and plan. .obvious weitage given to the work. .vacation cut short so that we can get back. .and when we are back. .rather than being happy and relaxed. .what we have is guilt and frowns. .
