An Indiana University student inspired the crowd and countless others with a commencement address that is now going viral. Parker Mantell completed his address despite a stutter that he had mostly kept hidden from his fellow students during his years in college.

“As a person who stutters, I can be no more certain that, in this room and in this hall, are thousands of people who far more talented at public speaking than I am. At the same time, however, I can be no more certain that the message I have to share is one that must be heard," he said.

"Doubt kills more dreams than failure ever will. If doubt were to be a disease, its cure would be confidence," said Mantell.

“Beethoven was deaf - imagine if he never dared to listen to his calling to compose music. Ray Charles was blind. Imagine if he had never dared to envision that he could touch the keys of a piano. Albert Einstein was dyslexic – imagine if he had never dared to embrace saying things differently by formulating equations. FDR couldn’t walk. Imagine if he had never dared to run. Imagine what you are depriving our world of if you never dare to achieve your purpose," he said.

Mantell joined Steve Doocy this morning, explaining that mothers and fathers of children with disabilities have reached out to him since his address, telling him about the positive impact the speech had on their kids.

Doocy lauded Mantell for the courage it took to unveil his stutter in front of 17,000 people at the graduation ceremony.

"I can't thank you enough for saying that, but in the end this is not about me or anything that I've done. This is about people and what I believe that they can become," said Mantell, who was chosen to deliver the speech after the university asked students to apply.

As for his career goals, Mantell said he wants to "help people" whether through politics or through law. Watch the interview above, and Mantell's full address below.
