A man in a hot air balloon is lost. He sees a man on the ground and reduces height to speak to him.
“Excuse me, can you tell me where I am?”
“You’re in a hot air balloon hovering thirty feet above this field,” comes the reply.
“You must work in Information Technology,” says the balloonist.
“I do,” says the man, “How did you know?”
“Well,” says the balloonist, “Everything you told me is technically correct, but it’s no use to anyone.”
“You must be in business,” says the man.
“I am,” says the balloonist, “How did you know?”
“Well,” says the man, “You don’t know where you are, you don’t know where you’re going, but you expect me to be able to help. You’re in the same position you were before we met, but now it’s my fault.”
(You can of course substitute other professions as appropriate.)
