1. When you come to Hollywood you have to think, "what am I going to give," not "what am I going to get." Most people come to LA to "get" things. They want something. Hollywood will not respond to you unless you are ready to give something. That needy energy of wanting to get, can be seen in an instant by the people in this industry. The more you are willing to give, the more excited and interested people will be in you.
2. Hollywood runs on energy. If you don't have a great positive energy that is radiating out of your body, you will likely be unemployed because positive energy is the Hollywood currency.
