Close your eyes and think of the last social gathering you attended. You were introduced to someone and you exchanged names. What was the next question asked? Most likely it was “What do you do?”More than any other aspect of your life, your work defines you. Whether you're self-employed, a stay-at-home mom or dad, a telecommuter, or part of the office-bound workforce, work occupies your mind and your time. When your mental or physical health is compromised, such as when you have depression, you struggle to get through the day, and work changes from a source of fulfillment to a source of frustration.
