I think the main idea of this speech, is that you need to find what you love to do in life, otherwise you'll never feel satisfied with yourself. Everyone has a purpose, and it's important to find yours. The most important things about what he spoke about, was that he got up and kept going despite everything that tried to set him back. Dropping out of college, getting fired from his own company, even getting diagnosed with cancer, none of these things stopped him from doing what he loved. He didn't let anything stop him.
I think that it was a very great speech from a very prestigious man. He told stories from his own life to address very valid points for a young, graduating college class. He told them things that they can use for the rest of their lives.
