Interview with Mr.?

The other day I was speaking to a man who directed shows in New York and he gave me some tips to make it big. This man said to never pass up and opportunity... ever and little time that you are in a theater you are putting your foot in the door. He also told me to be well versed in all aspects of theater the acting and technical side. The technical side of theater is and art form equal to or greater than acting. And by partaking in the technical aspects of theaters it allows you to make connection with people to get possible other jobs. This would be very hard to do if you where only an actor. So getting your foot in the door by any means necessary is a must weather its acting,pulling ropes, or moving sets, it gets your name out there in this big city New York. What is the technical side of theater? How do you hear about jobs? Source preferred to remain unnamed.
