It is very important to have a business plan in any endeavor. Especially in the voiceover industry there is a subjective element that can feel elusive and very arbitrary. This presents a bit of a dilemma.
How do you keep from getting depressed? How do you find your niche ? What should you be looking for? Here is one point of view that I personally have found very helpful. when I was very young, an old timer said this to me. "Ok, you're going into this crazy business...just find one person/company that likes your work and stay there...then find two more people that like your work and stay there ...AND don't waste an ounce of energy on anyone that doesn't want to hire you! THEY AREN"T your people ya big dope!" We don't need everyone to like us/cast us. We fit in with the people who do like our work and that is simply what we should look for and not worry about the rest.
