One thing about being a stand-up is it's a one-man show. You gotta do everything. You're the producer, writer, director, and the actor. You just gotta be out there and perform and give your all. It's such an honest form of art that it just taught me so much, and it kind of prepared me for manhood at an early age.

This quote is talking about being a stand-up comedian. It means that when performing stand-up comedy, a person has to take on the role of all of the people who usually work together to create a performance. They have to both create the performance and deliver it. Doing this builds confidence and teaches young people valuable lessons about life, including how to take responsibility and be an adult.
