(CNSNews.com) - Donald Trump, Jr., describing himself as "the son of a great man," urged the nation not to underestimate his father -- "a man who has a track record of accomplishing the impossible."

"We're still one country. And we're going to get it all back," Trump told the Republican National Convention Tuesday night. "We're going to get it back better than ever before. I know we'll get it back because I know my father.



"I know that when people tell him it can't be done, that guarantees that he gets it done. I know that when someone tells him that something is impossible, that's what triggers him into action.



"When people told him it was impossible for a boy from Queens to go to Manhattan and take on developers in the big city, rather than give up, he changed the skyline of New York.

"I've seen it time and time again, that look in his eyes when someone says it can't be done. I saw that look a little over a year ago when he was told he couldn't possibly succeed in politics. Yes he did. For my father, impossible is just the starting point. That's how he approaches business projects, that's how he approaches life."

Trump said his father will run the country the way he runs his businesses.

"He didn't hide out behind some desk in an executive suite. He spent his career with regular Americans. He hung out with the guys on construction sites...pouring concrete and hanging sheet rock.

"He listened to them and he valued their opinions as much and often more from the guys from Harvard and Wharton locked away in offices, away from the real work."

Trump said many of the top executives in his family's company started out in blue collar positions. And it was to those blue-collar workers that Donald Trump entrusted the business education of his children:

"We didn't learn from MBAs," Donald Junior said. "We learned from people who had doctorates in common sense."

Trump said he and his siblings are the only children of a billionaire who are just as comfortable in a tractor as they are in their own cars.

And later, he made the point that his father has "actually signed the front of a paycheck and doesn't just talk about it in theory."

At the end of his tribute to "my mentor, my best friend, my father," Donald Junior listed all the things his father will do as president, including working with "everyone" to pass legislation; reforming the tax code; repealing and replacing Obamacare; appointing judges "who believe that freedom requires limited government"; and putting America and Americans first.

Trump also said his father "will give us an immigration law that protects American citizens and gives them jobs."
