It is a maxim not to mix business with pleasure. However, some of the most successful businessmen and entreprenuers do just that. For them, it is not mixing business with pleasure. It is just that the business itself is pleasure. Take a successful journalist. For him, writing is pleasure. Take a successful playback singer. For him, singing is pleasure. Take the most famous baseball players. For them. playing is pleasure. Take the most successful businessmen. For them, getting into a new venture and pulling it off is the thrill and the pleasure. Those are really fortunate for whom the pleasure is the business itself.
