Mayor Julian Castro is admittedly a little nervous about speaking at next week's Democratic National Convention.
"I'm nervous about the whole thing," Mayor Castro said.
Who wouldn't be nervous? Mayor Castro will address an expected 35,000 people, and that's not including the 15,000 members of the media.
If that's not enough to leave him shaking, he'll also be sharing the stage with First Lady Michelle Obama.
Still, Mayor Castro says by Tuesday he'll be ready with a speech that will reveal his personal journey.
"I'm going to talk about my family story. The context of creating opportunity in America. How our nation has been the land of opportunity, and what we need to do in the future to ensure that that path to opportunity is sustained," Mayor Castro said.
Saturday morning Mayor Castro, with his wife Erica, daughter, and brother Julian by his side, said goodbye to a room of hundreds of supporters.
With all eyes on him, Mayor Castro said right now his focus is on making his city proud.
"I've had the opportunity to get the speech down and start to practice it, now it's just a matter of calming the nerves down and making sure that I do a good job on Tuesday," Mayor Castro said.
