BARRINGTON, Ill. - The students at Barrington High School received an hour's worth of advice from Republican presidential candidate Newt Gingrich  Thursday.

Putting aside his stump speech about  less dependency on foreign oil and $2.50 gas price promises, Gingrich told the group of students to "dream big" and pick a career doing something they love. Gingrich used his own life as an example of how to be happy.

"The fact is, I love life. I love getting up in the morning. I love seeing what the weather is going to be. I love animals. I love the process of interacting with people. I like learning," Gingrich said, after telling the crowd he was surprised at the reaction of the Arizona GOP debate when he said he was a "cheerful" person.

"So I really am basically cheerful every day because in my mind every day is cool, I am still here. And that is just a nice thing. I think if you enjoy life, you have extra energy. You are healthier. People who smile are healthier than people who frown. That is literally true. Statistically, you get fewer sicknesses if you smile," Gingrich said.

So Gingrich told the students that students should find something to do that they love and practice it. "You can't force yourself to something you hate," Gingrich said.

Gingrich told the students he'd been mocked by his opponents for his idea of a moon colony  and  parodied on "Saturday Night Live," but that did not stop him from having big ideas.

"You should define for yourself what your dreams are, and I would argue that one of the great weaknesses of American culture right now is we haven't had a conversation about the size dreams we need for a country of 305 million people, or 310 million people. You don't lead a country this size with tiny things," Gingrich said.

Gingrich told the students he looked to  President John F. Kennedy as an example of  how to inspire Americans to do great things.

"I think there are some aspects of John F. Kennedy's presidency and his campaign that really explain what I have been trying to do with much less success than Kennedy but in the same tradition, which is to take very large ideas to try to get America moving again, which was, in a sense, the theme of his campaign," Gingrich said.

Gingrich said that they had to be willing to learn new things every day and that he still learns new things every day.

"I certainly discovered this, here I am at 68 years of age. I've been speaker of the House, I have a Ph.D.  in history, I've ran for office for many years. I find every single day of the presidential campaign that  I'm learning new things," Gingrich said. "Things are different that I thought they'd be. I have to stop and say, 'What does this mean,' 'How do you do it,' and I'm suggesting to all of you, you have to have a habit of learning every day because the world is bigger than you are and it changes."
