Anything good is of value. Some people are uniformly charming and others are not. When a new chief takes over, his manners will be decided upon mostly in the first few days. Manners are of the surface and matter little when issues of importance arise. Still, real good manners have great value for one's career. Speaking about the stale customs of the society, someone said, "On birthdays everyone wishes ‘Happy birthday to you'. It is insipid and stale, but on my own birthday I have found it valuable and inspiring, knowing full well it is just a custom.
