Growing up, Donald Jr. says it didn't take long before he realized that his father was the Donald Trump. "I got to spend time with my grandfather from Eastern Europe," he says. "I spent a month or six weeks in Czechoslovakia with my grandfather, so I realized very quickly that the life I led in New York, in the United States, wasn't necessarily the norm. I think it was really important because it grounded us."
Although they grew up with many privileges, Eric says the Trump children learned not to take it for granted. "My father is amazing," he says. "He put us in the best schools, but he made us work. There was no free time in the Trump family. We either studied or we worked."
