Jeb Bush name-checked Charles Darwin, Albert Einstein and Mark Zuckerberg on Monday while telling University of South Carolina graduates that "young people and newcomers are often the great discoverers." 

The former Florida Republican governor's commencement speech -- short, optimistic and apolitical -- came the day after he'd said he planned to release 250,000 emails from his days in office. He will also write an accompanying eBook that he'll release next year. 

Bush's preemptive approach is one of the clearest signs yet of how seriously he is considering a run for president and allows him to address potential areas of criticism before opposition researchers dig in. 

On Monday, Bush made no references to his own political future, but did sound a number of optimistic notes -- and he told the new graduates not to fear failure. 

He said graduates shouldn't "be afraid to shake things up," and that they should embrace a rapidly changing economy even when doing so is daunting. 

"Most of America feels that way -- you're not alone. And in many ways, that's OK. Because that anxiety can be positive," he said. "When you're thrown into new situations, you don't just challenge yourself. You see things that other people might not see." 

The point of his speech, Bush said, was to tell graduates to "dream big, don't be afraid of change and find joy everywhere you can." 

And they shouldn't see their ages as impediments, he said. 

"Darwin was 29 when he developed the theory of natural selection. Einstein was 26 when he developed the theory of relativity. And Mark Zuckerberg, for crying out loud, was 19 years old when he developed Facebook," Bush said.  QUESTIONS:
