“I started beatboxing when I was a junior in high school.”

“It wasn’t until I was on Forbes and like in movies and doing these big brand partnerships, it took a long time for them to accept me.”

“You might have never heard of me before, but I promise you, I’m a force to be reckoned with and I’m gonna get there one day.”

“I’m a lot more than a beatboxer. I’m really talented in beatboxing, but I think my personality is a lot bigger for that.”

“If I’m a beatboxer and my only outlet is TikTok, I’m gonna make a song, a beat every single day. And so I said, I’m gonna make 365 beats and then I ended up making a thousand that year instead.”

“I expect even the people that are [reading] this right now, you don’t know who I am either. You might have never heard me before, but I promise you, I’m a force to be reckoned with and I’m gonna get there one day.”
