The thing is when job becomes something you feel forced to do it becomes a futile ardour necessary for survival. Most of the people who work in 5-9 jobs are not even interested what they do. First you get to love what you are doing. Where you work should make you feel as if you were at home. If it is not like that there will always be lack of motivation for sure. However you cannot keep such people from working since we all strive to make a living.
