Bingo. Something I got from reading his book, "Art of the Deal". He wanted to take over the restoration of the Wollman Ice Skating Rink because he wanted his kids to be able to use the rink and he saw the city was having one failure after another as it brought on construction companies more interested in the contact money than the job itself.
He said in the book that he know nothing about building outdoor ice rinks, but he knew how to find the best people for the job. He'll talk to these people to then come up to speed himself on whatever the topic might be. Basically, he's the definition of a good manager.
Agreed... I read the book in one weekend. It was fascinating to see him essentially apply things he said about business deal making 30 years ago to politics today.
