To solve a problem, you have to be able to state what the problem is or at least say the name.

I wrote 'The Art of the Deal' and numerous other books. Some were number one best-sellers. I guess 'The Art of the Deal' is the best-selling business book of all time.

I pledge to never sign any trade agreement that hurts our workers or that diminishes our freedom and our independence. We will never, ever sign bad trade deals. America first again. America first!

The old saying that "success breeds success" has something to it. It's that feeling of confidence that can banish negativity and procrastination and get you going the right way.

Mexico continues to make billions on not only our bad trade deals but also relies heavily on the billions of dollars in remittances sent from illegal immigrants in the United States.

I am proud to say how many people I employ. And the United States first, second and third generation Mexicans are just beyond reproach, spectacular, spectacular hardworking people. I have such great respect for them and their strong values of family, faith and community.

Things change. There has to be flexibility. Let me give you an example. President Xi, we have a, like, a really great relationship. For me to call him a currency manipulator and then say, “By the way, I'd like you to solve the North Korean problem,” doesn't work. So you have to have a certain flexibility, Number One. Number Two, from the time I took office till now, you know, it's a very exact thing. It's not like generalities.
