On our last cruise (on Royal Caribbean) the Activities Director seemed to have sooo much fun. She ran the Karaoke that I participated in and also Zumba that my wife went to. I think I can tell the difference between someone who smiles because that's their job and someone who really likes their job. She got a kick out of my singing Frank Sinatra's "New York New York". Whenever I saw her at a distance interacting with her cruise peers she seemed like she was right where she hoped to be in life.
I know Cesar does not want to be an Activities Director but I'm building up to my wish to agree with
@MinnieM123 re. when working with others that you like..... that feeling of "being part of a group/team"....that can make life enjoyable. A good boss is important in any line of work
