I went to a fabulous CD Workshop with one of my favorite CD's recently, who re-affirmed the comment that acting is "a numbers game". Yes, the entertainment industry is a numbers game, just like every industry out there. In the actors' case, the more we audition, chances are good we will book more.
But, we have to be strategic with this to be effective, which means we have to have a strong foundation - a sound business plan, have a focus, be strategic and tactical (Dallas Travers calls it having a "laser beam focus - being targeted with our marketing) combined with a healthy pursuit of our craft (classes and practice). Otherwise, we are just spinning our wheels.
Being strategic and doing the hustle will get you from point A to point B much faster than being without direction.
