Jobs play a HUGE role in life. There are few things that you do with your life that take up so much of it. If your job and your bed are good, life will be good, for the most part. Sleeping takes up roughly 33% of all of your life. Your job often takes up about another 33%, especially in countries where long hours and six and seven day a week workweeks are expected. The remaining 33% is all kinds of things, like family, friends, eating, bathing, commuting, hobbies, television, video games, etc.
