Nobody ever said on their deathbed: "I wish I would have worked more."
As an employer, I actually discourage workaholics. I much prefer people who have a balanced life. It tends to make them happier and more productive in the long run.
Life is short enough as it is. I believe an honest days work for an honest days pay is good enough. If you balanced your work with your health, I think you would be amazed at what will happen, in both your personal and professional life.
I work for the Department of Redundancy Department
