10 Things You Learn Reading Donald Trump's 'The Art of the Deal'

NEW YORK (TheStreet) - Donald Trump's best-selling The Art of the Deal came out in 1987, but feels like it could have been written yesterday. The 2016 Presidential hopeful hasn't changed much since then. He's still jetting around and making deals -- huge deals -- and talking about them in much the same way he talks about his political campaign today. 

"I don't do it for the money. I've got enough, much more than I'll ever need. I do it to do it. Deals are my art form," he writes, in the book's opening line. It goes on from there with pages of Trump gems (although, in his case we're probably talking about diamonds). 

Trump has claimed that the book, originally published by a division of major book publisher Hachette, is the No. 1 best-selling business book of all time (a claim that has been proven false -- it is estimated to have sold about a million copies, a fraction of titles like How to Win Friends and Influence People and The 7 Habits of Highly Effective People). 

But if Trump wins the Republican nomination or the presidency, you can be sure that this enlightening look into Trump's personality will again fly off the shelves. 

Here are some things you can learn reading Trump's master work. 

1. Trump is the same now as he was in 1987. 

Just look at the first line of the book, "I don't do it for the money. I've got enough, much more than I'll ever need."

How many times have we heard during Trump's campaign for the Republican nomination that he's rich and successful?

From Trump's announcement speech in June: "I don't need anybody's money. It's nice. I don't need anybody's money. I'm using my own money. I'm not using the lobbyists. I'm not using donors. I don't care. I'm really rich."

Talking to CNN in July about his financial disclosure: "People said, 'Oh, well maybe he's not as rich as everybody thinks you are.' Well, it turned out I'm much richer."

An August Huffington post article cited this as his mantra: "I am rich. I am successful."

Want more? Okay: Despite Trump releasing financials claiming to be worth about $9 billion in June (and Forbes pegging the true figure as much lower), he has since claimed to be worth more than $10 billion.

On the issue of being rich and successful, at least Trump is not a flip-flopper
