Stand up and know your worth

Always stand up for what you know you're worth. We're going through that with a long time client right now. And remember your name and reputation is part of the brand/service you represent. There are people and companies out there that will respect your values and what you offer them. People think I'm a hard ass, but at least I know what my company, my products and services, and my crew are worth and not afraid to say so. Go for quality clients, the ones that treat you with respect, regardless of how much they're paying. Go for projects that make you happy and challenge you, as long as they're doing good by you, it's good. Finally as you create your client base, stay close to the ones who value and respect you. 
 
And yes, as an actor and artist, I have had to say no many times over money, work conditions, and the fact that I thought the production or show was not up to my standards, for whatever the reason. It's good to have standards, one needs to learn when to be flexible with them as needed.
