The constant hussle
Every actor and actress that has lived the life in a career in performance knows exactly what it means to hustle. Another word they may use would be "relentless" in fact, because that's exactly what it is. Relentless Hustling. You can't wait for opportunities to come to you in this business because they will never come. You have to chase the opportunities and make ones for yourself. This business is all about the hustle. Having job on top of job just to make ends meet while pursing your dreams is the normal routine of an actor. Not one route is right or wrong, and there are so many ways to do it. From waiting tables, to substitute teaching, to being a tour guide of the hub of a city you live it, to photography to whatever it takes to provide and all while going to audition after audition never taking a break.
Your drive is so necessary. Especially when living in cities like this. Where you have to offer something different to a director that doesn't want to see the same thing over and over again. They want to see something that sparks their interest. So instead of changing yourself to meet what you think are their standards, be who you are and take any opportunity you can get. And no matter what, hustle!
