A lot of people seem to dislike their work, yet ask many people and they define themselves by what they do for work
Sometimes the work most people engage on is not what they really desire to do but have no choice than to do something to earn for a living. No doubt most of this jobs buy your time because you have no choice than to be present in the required time been ask to which is an agreement between you and the company in other for you to fulfill to avoid sanction or query.
Before contentment in the job, the job has to be done. I have found a lot of younger people don't want to learn the job required, so don't build a work ethic. This means they never end up content.
