If you want to understand what leadership is all about, don't, I advise you, go and pay through the nose to listen to what I call those wandering gurus.
You know the sort I mean - gift of the gab, glib, smooth, all the cliches going, the top know-alls of the bullshit industry. They spew out psycho babble and economic wizardry but are little more than phoney 19th century horse doctors offering elixirs to cure all known ailments.
Strip away the veneer and you find their mind-bogglingly expensive lectures and books expound little more than common sense.
No, if you want to know about leadership, go and listen to legendary former rugby player Willie John McBride.
He was over last week giving a speech at a pre-Lions departure lunch organised by the almost equally legendary Greville Edwards.
The man has huge presence. There is no chattering at the back of the room when Willie John is talking. He demands attention.
There were plenty of gags, of course.
"I seem to become a better player as the years go by," he quipped with typical modesty.
Or, of one of the 1971 Tests, still the only series the Lions have won in New Zealand, he recalled: "Ten minutes before kick-off Gerald Davies was combing his hair in the mirror. I didn't want to let the forwards see this so I took them to one side."
And then there was his line-out jumping technique and his arrangement with hooker Bobby Windsor on a South African trip.
"Bobby knew how I liked it delivered - low, fast and crooked."
But there were also some management gems among the jokes. He told how among the squad there were men of all backgrounds - coal miners from Wales and "even a couple of Londoners".
Nevertheless they had loyalty to each other, their coach and their manager, and that stood whether they were in the first XV or in the stand watching.
"They were a great bunch of men and they were winners," declared Willie John.
Loyalty - isn't that an old-fashioned concept?
In many spheres of life it is a quality which does not seem to exist any more. Too often in both today's business and sport it is every man for himself - more's the pity.
Many bosses pay lip-service to teamwork while seeing it as a threat.
And he had some advice on man-management slotted somewhere in the draw marked 'work hard, play hard'.
In those days they went on very long tours.
He noted: "We worked hard but we had some piss-ups as well. You cannot live on that platform of intensity."
Which I interpreted as meaning that today's management demands everything of you all the time, and it's just not possible.
But Willie John also asked the question of the current Lions in New Zealand.
"Who will crumble and who will step up?"
And that applies so much in work. When the going gets tough, who will crumble and who will step up?
If managements can identify the hard men from the hangers-on, something all too few seem capable of doing, then they won't go far wrong.
