How can we find joy in work? By working for oneself? No; it is not possible to find that continuous joy in work through selfish motivations. Frustration and ennui are the end of all selfish motivations. Frustrations and nervous breakdowns are the end of a self-centred life.
It is from the human mind itself that both good and evil come. So, a little attention as to how the mind is behaving, in the context of work, is absolutely essential for all people today. Otherwise, collective life will become difficult, group life will become difficult; life between husband and wife will become difficult, because both, or either of them, has not looked into the mind at all; they have been looking outside all the time.
