Paul also said that a presidential campaign would result in less time at home with his family.
"It is a big job to do, to run for president," he said. "It would take traveling around the country."
Paul told the student that he will not decide on a potential 2016 White House bid for another year, but that there's a 50 percent chance he'll run.
"It's probably 50-50," he said about the odds of him running. "We are thinking about it and looking at what it would take to run. It's a big job. But we probably won't make our decision until about a year."
