The most successful comedians usually come from stand-up. On small stages in trashy dive bars, aspiring entertainers have a relatively consequence-free opportunity to put their act and endurance to the test. With enough 5-minute open mic opportunities, the smartest performers learn what works and what does not. Over time and through plenty of failure, artists refine an authentic routine and stand out against the noise. They find their voice. When it comes to successful entertainment, original voice is everything.
If you dream of entertaining, embrace the small venue. Find a small stage through which you can practice and refine your voice. The Internet counts.
