As I remember my grandma used to say : "A sound mind in a sound body "! She believed that work helped us to be active and to be healthy. As for me work is an activity that helps me to be physically and mentally healthy. Of course we get money for the work we do . But sometimes a person has a good well-paid job but it doesn't bring him pleasure. And on the contrary one does the work he likes and gets little money. It is rather difficult to find the golden mean.
