On moving to NYC from his small hometown in Georgia: “It was crazy. I didn’t speak for three days, and if you ask anyone around me, that’s miraculous. I was terrified. I left on my own, no family, no friends … I left everything to see what would happen.”

On his jam-packed schedule: “The travel is hectic. In June, I already have to go to 13 countries, which is great, but it'll be all work and no play. But [I am] just appreciative of the work. I don't get paid to complain. But I have a really cool job coming up, and my family is going to be a part of it, so I'm stoked about that.”

On the future: “Oh yeah, I can't wait to one day have a wife and kids … but not right now. I'm just doing me, and staying focused on my career right now. So just flying solo at the moment.”
