Personally, I think everyone can learn someone from everyone; regardless of style and their audience (kids, young adults, adults only, etc.) Even from that magician, you can observe his timing, delivery style, audience rapport, sense of confidence, etc. Even if a comedian is not my cup of tea, I can still learn from him. What’s working? What’s not? Is the audience responding? How does he handle hecklers or interact with the audience in general. I don’t have to like his style to observe his skills and appreciate his talent. Learn from one and all. But always remember to be yourself! But being true to you and your own style doesn’t mean you can’t learn positive and negative things from others!
