The worst things in history have happened when people stop thinking for themselves, especially when they allow themselves to be influenced by negative people. That's what gives rise to dictators. Avoid that at all costs. Stop it first on a personal level, and you will have contributed to world sanity as well as your own.

I think that my stance on having people come in to this country that we have no idea who they are and in certain cases you will have radical Islamic terrorism. I'm not going to have it in this country. I'm not going to let what happened to France and other places happen here. We have hundreds of thousands of people that have been allowed into our country that should not be here. They shouldn't be here. They have no documentation and they were allowed under the previous administrations, they were allowed into our country. It's a big mistake.

I think I have a big advantage. But it's certainly a three-person race. And you have a couple of other people that are very talented there too. So we have a five-man race. And I think that it's going to be not easy. I have a big advantage. But a long way from being won.

You cannot be successful without passion. If you don't love what you're doing, if you don't have passion for it - forget it. Do something else. You'll be much more successful and you'll lead a lot happier life.

Marco Rubio, as an example, he's got no money, zero.I think that's fine, that's OK, maybe it's good politically to say you owe money because you overborrowed on your credit cards. He's got nothing. I mean, he's got nothing.

I could never have imagined that firing 67 people on national television would actually make me more popular, especially with the younger generation.

Jeb Bush brought it up at the debate and he was doing it very well, and all of a sudden, I don't know what happened, but he got shut down.
