This is a conservative and structured approach. This native understands that to succeed he must adhere to moral, ethical and social codes that may not completely agree with his own personal code of convictions. He will learn to navigate this business requirement without undermining these personal convictions.
In other words, this guy knows he’s gotta deal with people carefully. He might lock away his own personal responses in order to be diplomatic, but he will very much be aware of where his own personal line in the sand resides.
He will be very firm where that line is concerned. He will make no apologies for his personal boundaries. If people seek to work with him they will become very much aware that the line between personal and professional exists and, sometimes to their dismay, the repercussions if they attempt to cross those boundaries.
