God knows the human mind and body was not made to function in the unnatural world of the rat race. A job or career can easily take over your whole existence. Even your values and social calender can be dominated by a stressful work load. We need to be mindful of this.
I firmly believe in rest and relaxation. Vacations are crucial but you can also take breaks and three -day- weekends. Remember that rest is an important part of work. It is good to be home.
