Some people are lucky enough to find meaning in their work. That is a luxury. Many people need to work to live and will happily find meaning in other facets of their lives. But people shouldn’t believe that work is the only sort meaningful activity in life.

They may or may not. Many people are happy when spending time with loved ones. You can live a happy life and never work "hard". Just do your job and be happy. There is nothing wrong with tbat.
