Managing technical professionals: work/life balance

SIMPLE math tells us that most of us, who have a working career, spend more time at work than at home. I know that it sounds like a cliché, but that is why it is important for us to wake up every morning knowing that when we go to work, we will be doing something that we enjoy and have some sense of satisfaction while doing it. It is also why one of our responsibilities as a manager is to make sure that our team members are working on projects that match their skill sets, that they are sufficiently challenged, and that they also have some sense of satisfaction while working on the project rather than being stressed out.
